Wheaties presents Dimension X. Adventures in Time and Space. Transcribed in Future Tense. Stage 9 Dimension X. Another in the Wheaties big parade of exciting half-hour presentations. Just about the time you're getting up tomorrow morning, you know what's happened? You've been without food for so long that you gotta get more if you're going to get your work done. That's why first you need your Wheaties. Sure, Wheaties. Because when you dip into those golden flakes, you're getting real whole wheat. Yup, every single Wheaties is a kernel of wheat. And you know what that means. Vitality for working well, feeling well, looking well, whole wheat energy, whole wheat vitamins. All the goodness of plump whole wheat and crisp little flakes that are mighty nice to meet any morning of the week. So be good to yourself. Tuck into the Wheaties at 7 a.m. and see if you don't feel the difference. Have yourself breakfast of champions and see how Wheaties at 7 can help at 11. Come on now. Try them. What will happen when man, finally conquering the galactic distances of interstellar travel, finds life on the strange worlds across the universe? Will he discover civilizations of incredibly advanced scientific knowledge or primitive cultures deep in a stone age of savagery? Here is a story of the relation between men of our world and beings from beyond the stars. On the desk stood a yellow bowl, the profile a simple curve clean and sharp. His body was thin without fragility and the beauty of its shape was matched by the glowing intensity of the glaze, a glorious transparent yellow, soothing his sunlight, yet glowing with the fire of a volcano's core. The desk belonged to Michael Tom, Regional Administrator for the Department of Interplanetary Affairs. Bowl? Why, it's a souvenir. I got it many years ago on the planet first. I'd been out on the channel planet in the frontier servers for 19 months. When my transfer came through to FERSC, I was surprised to see that I'd been promoted three graves and my orders read to report to the Regional Officer as Assistant Resident. My ship came in at Panolpan Spaceport and I was met by the office car and show port. Mr. Tom? That's right. I'm Wiracheck, sir. Welcome to FERSC. Thanks. Well, I didn't expect to find a 1992 Rolls here. The resident had it shipped out in part. Mr. Covel changes every year for the new model. Pretty smooth. Hey, this is certainly different from the channel planet. Nothing there but ice, frost, please, and the dullest aborigines in the system. Well, you won't find the aborigines very dull here. What kind of people are they? The Metoon? Well, they're humanoid. Very close to us, systemically. Tall, sort of amber-colored and graceful. Oh, is that one, the girl balancing the bowl on her head? Yeah. Yeah, she's a me too. There isn't a very big human population at first. Oh, well, well. Looks like Mike Tom has found a home in this service. You haven't met Mr. Covel yet, have you? What do you mean by that? Oh, nothing, sir. Nothing. Look, Wiracheck, if there's anything wrong, you'd better tell me. Well, there's nothing, sir. Nothing you won't find out. It's just that Mr. Covel is a very forceful personality. Very forceful. We drove through Penalpan, threading our way through narrow streets between rows of low houses of reed, parchment, and wood. Canals of green water laced the city and the bridges trailed ivy and orange flowers. Suddenly we turned a corner, and there on the bank of the main canal was a large concrete and glass building, Earth Star. This was the district office, and in a room that gleamed with black plastic and glass, I found George Covel's senior residence. You're Tom, Michael Tom? Yes, sir. My last junior took off for the hills with a dancer from a Mitu and Grog shop.  That clear? That's clear, sir. And don't get edgy with me. Sit down. Now, listen, Tom, I'm easy to get along with. I like things done, done right the first time. Got to give a good example for the gooks. Gooks? Yeah, the natives. I don't know what's good for them. I brought in a high-grade silica yarn to replace the root fiber they were using at fishnets. Took me three months to talk them into using it. I thought the Bureau policy was to avoid introducing Earth technology to stable cultures. Yeah, that's what those boneheads of the main office say. They don't have to live here. Have you seen those pigsties they live in? There isn't a concrete building on the planet. The Mitu in delegation, Mr. Covel. Tell them I'm busy for 15 minutes. Yes, sir. Well, I'll be going along then, sir. Why? Well, if you're busy. Forget it, forget it. I always let those gooks wait at least 15 minutes. Softens them up. They're not hard to handle, if you know how. I was assigned to pest control, a duty Covel considered beneath his dignity. In the next few weeks, I carted rat poison and insect spray through the poorest sections of an old man, where the trees ended and the plains stretched out to the Cookmount Mountains. It was there that I first heard of the potters of first. I had found a pottery bazaar, long shells of jars of every size and shape, crocs, paper thin vases, bowls, damejons, tankards. The glazes were remarkable, deep glowing colors. And yet something was missing. I looked up and down the shelves. Mr. Tom, is anything wrong? No, no, it's just... Oh, I've got it. There isn't any yellow. Yellow? That's right, there are no yellow glazes at all. They have every other color, ruby, green. There's a jar that's translucent, but no yellow. Oh, maybe it's a superstition. It could be. Yellow might be connected with death or a disease. Well, you can find out, Mr. Tom. Here comes a me too, and she probably runs a place. May I help you, sir? Oh, you speak English? We trade with the Earth's colony. Your wares are very beautiful. For example, how much is this bowl? Seventy-five credits. That much? They are our ancestors. And to sell them as cheaply as wood or glass would be irreverent. Your ancestors? You mean the bowls? Yes. Uh-huh. Tell me, where's the pottery made in Pinot Pong? No, back there. In the mountains? There our ancestors go, and the pots are brought back. Aside from this, I know nothing. The meat you infear, the potters. Why? No one knows what lies beyond the first hill, Earthmen. Sometimes we see the glow of furnaces. And when there are no dead for the potters, they take the living. The living? The potters now. What are they shouting? That they have sold all their wares. That they will ride back to the mountains now. Hey, big devils, aren't they? Red-haired. They are very strong. I think I'll visit the potters one of these days. No, Earthmen. No, why not? It is dangerous for you. They've guarded their secrets from all Pinot Pong. They are very fierce. I told you to get the estimates for that power plant. I put them on your desk, sir. Oh, yeah. And so you did. Say, what do you know about the potters back in the cookmunks, Mr. Coville? Oh, they're a tribe of bandits or something. I was at the bazaar today. A girl called the vases Ancestors. It seems strange. Ancestors? Well, it probably has something to do with religious death rites. They take away the dead bodies and cremate them for a fee or trade goods. A girl said that when they don't get the dead, sometimes they take the living. What? Well, so that's it. What, sir? Rating. Not every month or so, a couple of me too and turn up missing. The whole city clams up like tongue-tied parrots. For two years, I've been trying to track it down. Tom, these potters must be behind it. Rating, huh? We'll see about that. No, we don't know anything. Death... Well, we will. Get where, check to roll out the copter. We're flying out to those mountains. I'll put a stop to this if I have to blow them clean off the planet. We'll never find a village in that mess down there. Look at those cliffs. There's a smoke trail over there to the right. Potters need kills, kills need heat. That's a volcano, not a chimney. Let's try out along that ridge and we'll go back. Wait, I think we found them. Where? At the base of the volcano. Look close, you can see buildings. Yeah, yeah. Set it down. Should we land, sir, there? They're supposed to be pretty rough on home ground. We're official representatives of the system. Remember that. That might not mean much to a tribal mountaineer. Don't argue with me, Tom. Land. Get your pistol ready. I don't see anybody. The village is deserted. They're hiding. The potter's all right. There's a heap of old broken jars. But I don't see the kill. They'll stay here till something moves. What's that? One of the potters. Wait a minute, here they come. Three of them. You cover them, Tom. I'll do the talking. Hey there. You. What brings strangers to the village of the potters? I'm Coville, chief of the Planetary Affairs Bureau in Penalpan. This is an official visit to see how things are going with you. We make no complaints. Oh, I've heard reports of you potters kidnapping me too. Is there any truth in that? There is an ancient agreement. The potters are granted the bodies of the dead. And occasionally, when the need is great, we do anticipate nature by a year or two. You mean you admit it? The soul lives forever. In the bowl it's beautified. What do you mean? Look here, just what do you do with the corpses? Our glazes require lead, sand, clay, alkaline, spar and lime. Oh, but the lime is at our hand. And this we take from the bones of the dead. I see. Well, we don't interfere in any native customs or rights. Corpses, that's between you and the me too. If you need lime, I can ship you in tons of them. Natural lime is a poor substitute for fresh, live bones. The spirit of the person is in the bones and it passes into the glaze and gives it an inner fire. Well, you listen to me. I don't care what you use as long as there's no kidnapping or murder. Tell me, Potter. I don't see any furnaces. Where are your kilns? Our firing is done by the great monthly burn. You mean the volcano? Yes, Earthman. Once each month the heat roars up white and glowing. I see. Potter, why don't you ever use yellow glaze? Yellow glaze. We have no metal to give the pure rich yellow the color of the sun. It is strange, Earthman, that you talk of the yellow for my people have sought the sun glaze for thousands of years. Listen, if there's any technical help you people want, that's my business. But there'll be no more murder. Necessary, I'll put a stop to the potting altogether. Your words are not friendly. I'll die! Don't think I can, Dork. I'll drop an atom bomb down the throat of your volcano and cave in the whole mountain. We'd better pull out, Mr. Covey.   My job is to protect everyone on this mud-hole planet. And that includes the me too. Get back in the cockpit, Mr. Covey. They're getting ugly. Fire over their heads, keep them back. Quick, get in, sir. They're scared now, but in a minute they may jump. All right, let's go. Don't worry, Tom. Now those cooks know who's boss. Now, sir, we won't have any more trouble from the potters. Covey kept me pretty busy the next few weeks. But I got to spending a good deal of time at the pottery bazaar with the girl. Her name was Sue Then. She was interested in everything I had to tell her about the rest of the galaxy. And I was lonely. So I got to looking forward to my visits there. I was on my way there one evening when suddenly I heard shouts down the side streets. I hurried toward them pulling out my gun. And then I heard the deep cry of the giant potters and the crack of holes on the cobbled streets. Suddenly a group of writers burst around a corner and charged down on me. I hurried to the pottery bazaar. Sue Then was gone. This man. She's not here. They took her. She has gone to her ancestors. Did they kill her? No, no, they have taken her to the hills. But soon she will live forever. Her spirit wrapped in the glorious glaze. Sue Then. There is nothing to be done when the potters take you. It is the end. I've been raiding again, huh? Four me too on tonight. Bring the copter around in front. It's ready. Tom, I'm gonna break out the atom bomb from the arms locker.  I'll teach those murdering devils a lesson they won't forget. But the meat will come crawling to the city on their hands and knees. I know how to run this planet. Dimension acts. Well, continue in just a moment. Friends, this is Frank Martin, the Wheaties' man, and I want you to know an associate of mine, Ed Printers. Okay, Ed. Folks, I'd like to have you meet a good friend of mine and a prominent member of a fine little organization known as the Chicago White Sox, Mr. Lucius Benjamin Atwood. Oh, Ed, don't say it like that. Whoever heard of a ball player named Lucius. What if I went around calling you Paul Edward Printers? Let's just make it Ed and Luke, huh? All right, Luke. Say, just how long have you been with the White Sox? Over 20 years, Ed. Golly, I've played in darn near 2,500 games. Then it bat almost 9,000 times, man. I'm from way back. Well, Luke, you don't look it. How do you keep up the pace, anyway? Well, Ed, I sleep good. I eat good.  Wheaties about four mornings a week. Those little old flakes put a lot of snappy even in an old time like me. Must be because they're 100% whole wheat. I sure like wheaties and milk and fruit. You know, Luke, that's exactly what I hear from a lot of ball players and plenty of other people, too. Now, wonder they call wheaties the breakfast of champions. Thank you, Mr. Prentice and Mr. Luke Appling of the Chicago White Sox. Mighty nice of you to say those good things about wheaties. Now, folks, you and I may not be playing baseball for a living, but we can use those whole wheat wheaties, too. Step around to the grocery tomorrow yourself for wheaties, breakfast of champions. Breakfast for you. Dick, swing over it. Shall I pull a safety on the bomb? No, no, hold it. But Mr. Colwell said we... I know what he said. They got a girl down there, and I'm going to get her out alive. And I'm going to start by trying to talk with that seven-foot red-headed potter. All right, we're a check. Set her down right in the middle of Main Street. Here they come. Tall one to the chief. Oh, this is the insolent lordling again. Come on, out of the copter. Good. We are in need of bone lime, and yours will suit us well. They're closing in, Mr. Tom. Prepare your soul for the great burn. Stand back. I'll kill a lot of potters, and you'll be the first. Ha-ha! You need to understand that we can punish you. We potters do not fear death. Death is merely eternal meditation from the glass. Potter, listen to me. I didn't come here to threaten but to bargain. You have a me too and girl. Is she still alive? She still lives.  We can do that easily. If I'm harmed, the next bomb will drop on your village. I've come down here against his orders to bargain. Bargain? With what?  Potter, I can give you the secret of the yellow blade. Empty words. No, the truth. In exchange, I want the girl and the other me too and you've stolen, and your word, not to raid again. How would we get lime? We've told you, we can ship it in. Pure lime, as good as yours. Do the potters of first want the yellow glaze? Why, that has been the goal of the tribe of potters for a thousand years. And if I show you the yellow glaze? Earthmen, if it comes clear through the burn, I agree to your bargain. If it does not, your spirit will be lodged forever in the ugliest bowl we can spin on the wheel. It's a bargain. All right, we're a check. Disarm the bomb. Disarm it? Mr. Tom, you're crazy.  I mean, nothing left to stop them. Nothing but the yellow glaze. Yeah, but do you know how to make it? We'll soon find out. I've been doing a little reading on the subject lately. Reading? Holy smoke. Enough, Earthman. I will take you to the potter's shed. If your glaze is the bright yellow of the sun, you live. If not, you die. Come on, Racheck. Let's get to work. With what? You never made a glaze in your life. What are we supposed to work on now? Our last will and testament? Why did you come?  Maybe. How did you get in here? When I heard that you were here, I asked the chief potter to come. He said it would not matter. They would have all our bones soon. Cheerful, Zo. Hey, you stir this, Racheck. Yes, sir. They said you were trying to make the yellow glaze.  This goo may turn out yellow. It is better. No one on first has been able to make it. But I'm not from first. Hang on, Sufen, we're not dead yet. Earthmen, I'm glad you came. Although I wish you had not. Sufen. All right, Racheck. Call that redhead. Tell him I got his glaze ready. Earthmen, are you ready? Here's your glaze. Test it. You have six bowls of glaze. I'm no potter. This stuff ought to turn out yellow, but I can't be sure in one mixture. We will coat six tablets, one with each glaze. Then we will fire them. How long will it take?  How long can they keep that up? It's been hours. Tiles ought to be done soon. Earthmen, here comes the chief potter. It must be time. The tiles are cooled. It is time now to open the kiln and test your glaze. I know! The bargain has been made. The glaze is yellow or you die. I will open the kiln. Mr. Tom? I can't see inside. It's dark. All right, potter. Pull him out. What are you waiting for? I will remove the first tile.  Pull out the next one. The color of mud. And I'll wait a minute. What is the use? There is no yellow glaze. Get that next tile out. We made a bargain. Mr. Earth Brown, your glazes are worse than the creepiest work of our children. Prepare your spirits for the great burn. Now wait, wait. Look in there, the next tile. Get it out here.  I'll get it out myself. There. There, look at it. Yellow. Bright, shining yellow. There it is. The yellow glaze. We're in thunder, have you been? Mr. Cobill, I've been trying. I sent you out on business which should take two hours and you stay two days. Why? I got the four-meter and back and I made a contract with the potters. No more ratings. You what? I made a deal with them and it turned out to be a better idea than yours. You disobeyed. You deliberately... Tom, you're through here. Through with planetary affairs. Listen, Mr. Cobill. The man can't be trusted to carry out orders. Not worth a lead nickel to the bureau. Get your gear together. Leave on the next ship out. Yes, sir. Wait. Your own company time to four o'clock tonight. Until then, you obey my orders. Take the copter back to the hangar. Bring the atom bomb back to the armory. I can't. What? I've been trying to tell you. There's only one way I had to make that yellow glaze. Tom, what the devil have you done with that bomb? I gave it to the potters. What? It was a uranium salt that made the yellow glaze. The potters didn't have any so I gave them the uranium out of the bomb. That was part of the bargain. You gave that murdering tribe of gooks at uranium. You heard me. And if you think you could have used it better by blasting them out of that mountain, you're crazy. Why, you abysmal blasted imbecile. That's the only bomb we had.  If you want that uranium, Cobill, you can go out and get it. If I'm fired, I'm through now. Why, you frist mutt, you yellow-libered louse.  If you asked me, I'd say it would be dangerous business trying to get that uranium back now. We're a check. We're a check. Yes, Mr. Cobill. Yes, sir. Get the copter fuel. Give me a double holster and a full bandelier of ammunition. Yes, sir. Tom, when I get back, I'll see that you rot in the deepest cell in the Gallatin Tower. I'm going out now to those hills. I'm going to bring in that uranium myself. Two days later, Weracek came into my office. His face was pale. His hands shook with excitement. He's... He's here, Mr. Tom. He's here. Cobill? No, the chief potter. The potter. Bring him in.  Just bring him in. Well, potter, I was just going to the mountains to see you. Earthman, does that bargain we made still stand? Just a minute. First, I want to know what happened to my chief. He has not returned. A madman came to the village of the potters. He said you had no authority. He said he could not allow the potters to keep the heavy metal that makes glaze like the sunset. What happened to Cobill? Tell me. There was violence. He killed six good-wheel men. He was captured. I come to find whether our contract is good. All right, potter. The contract is good. It is bound by my word and by the word of my great chief back on Earth. But only if Cobill is returned. He must be brought back. Good. Then to steal the bargain I have brought to you the first bowl made with a new yellow glaze. It's a beautiful vase, potter. And now, about returning, Cobill. It is done. The madman is the lucky man, indeed. For his spirit dwells in the brightest glass ever to come from the great burn. You mean that Cobill? Here. I return him to you. The fiery soul of the madman has given lustre to an already glorious glaze. He will live forever in the shining light. On the desk stood a yellow bowl and the beauty of its shape was matched by the intensity of the glaze. A glorious transparent yellow glower of a volcano's core.

This episode brought to you by noble gold check out this free offer from my viewers ask yourself Are you on the investment treadmill? You know what I mean saving and saving and saving cash for retirement Well, guess what that savings isn't gonna be worth much by the time you retire cash It's trash you have to make money work for you If you feel like this could be the answer for you call the team at noble gold take out a qualifying IRA this month And they'll give you a solid gold 22 carat one-tenth ounce American Eagle bullion coin visit our website now at the link you can find in the description or pin comment Go right now and check out this free American Eagle gold coin offer Hello everybody and welcome back to another episode of going insane with drone tech if you're anything like me You definitely don't watch SNL and probably didn't see the latest episode this weekend with Elon Musk They're a bunch of unfunny partisan hacks who only see fit to mock Republicans or Republican presidents Never ever their dear leaders and the Communist.  He could have just as easily been making the 6 6 6 sign Which by the way somebody else has already accused him of so which is it is he making the white power sign or the Satan sign or is he just trolling one of the best reactions came from this unhinged blue check mark quote freelance writer and editor named Daisy Bayerger saying quote wait Did Elon Musk just like aggressively flashed the white power sign during the weekend update, please tell me I'm insane Please no really going to need you to tell me I'm insane. Oh, don't worry We will you are certifiably batshit insane And I have no doubt that you're gonna follow this tweet up with further proof Definitely never thought Saturday night live would send me into a tornado of existential despair But here we are I almost don't have words, but I will say that I hope his Tesla catches on fire and he dies What okay, not only are you definitely insane, but you may have just committed a crime Well, probably not a crime But she is wishing a horrible painful death on a person for the high crime of making an innocuous hand gesture That no doubt all of her most favorite people are also guilty of using I'd show you more of this crazy persons ranting But she made her profile private Probably a good move. How does this person still have a blue check mark? I mean, how does she still even have an account? I was banned from Twitter for saying that one of the people pictured inside the Capitol on January 6th carrying a Rubble flag should be executed which was obviously a joke I was making towards all the people calling for their heads But this blue check mark can post something like that and there's no ban hammer from Twitter Well, of course not because as we all know these rules are really just Justifications for them to silence their political opponents some other blue check marks weighed in on Elon's heinous act Saying quote it seems the defense of white power signs is that the people who see it are crazy conspiracy theorists Who can't recognize an old-fashioned contorted okay symbol not sir Why they think Elon must with flassing okay? Elon Musk did the white power hand gesture during the weekend update twice with each hand NBC got norm out of that desk for way less times are changing. I guess this whole white supremacy thing is very retro All right folks That's all I have for this one just wanted to cheer up your Monday with a little woke madness if I've done my job Please hit that like button, and I'll see you all tomorrow


Ukrainian armed forces will try to launch an attack on Belarusian capital Minsk. Russian military expert Alexander Kramchikin has told news.ru media portal. Kramchikin stated that Ukrainian armed forces could strike Belarus during a planned attack, stressing that currently the Belarusian army is much weaker than the Ukrainian army. In his words, Belarusian army will not be able to put up a strong resistance. Kramchikin emphasized that currently the Ukrainian army is superior than the Belarusian army according to all indicators. Last week, Ukrainian President Volodymyr Zelensky stated that the armed forces have almost enough assets and weapons to start moving forward and that Ukrainian defenders are primed for success. The planned counterattack could mark the most consequential phase of the war as Ukraine seeks to take back significant territory.


Good evening aspirants. Welcome to the Indian News Analysis brought to you by Shankar Ice Academy for the date 12th of December 2021. These are the list of news articles that I have chosen today for discussion. Now in this first discussion we are going to see about the 5G technology and we will see what implications it will have to the aviation sector. And in this second discussion we are going to see about two tribal communities from the northeastern states. They are the Chakma community and the Hajjong community. And then in this discussion we are going to discuss about molecular chaperones which are a type of proteins. And then in this next discussion we are going to discuss about the Pinaka rocket launcher. Then we will see about Raja Ji and few office accomplishments. And along with that I have three practice questions today. Then I have a quiz question also. So, pay attention to the discussion. Then we will have one mains practice question. So, without wasting much time now let us move on to the first news article discussion. So, our first discussion is going to be based on this article. It is a science based article. This article talks about the molecular chaperones and it also talks about what this molecular chaperones do in our body. See as the name itself suggests molecular chaperones are something that is in the molecular level. So, it can't be seen with the naked eye. Therefore, in this discussion we are going to understand about these molecular chaperones from the exam perspective. The syllabus relevant to this discussion is given here for your reference. Now first to understand the molecular chaperones we need a basic understanding of DNA. So, what is DNA? It is the deoxyribonucleic acid. It is the molecule that contains the genetic code of organisms. So, DNA is the material that carries all the information about a living thing that is needed for functioning properly. For example, DNA in humans determine things such as what color our eyes should be and how our lungs should work etc. Now this DNA it will be converted into messenger RNA in our body. This messenger RNA is in short called as mRNA. Now this process of converting is called as transcription. Now this process is the one by which the information in a strand of DNA is copied into a new molecule of messenger RNA. So, the information from DNA is copied to messenger RNA and you saw that DNA holds the genetic information of a living being and now this information is made into copies in the transcription process. Now after this process proteins will be formed. So, that means mRNA forms the basis of protein formation. Here understand the terms it forms the basis of protein formation. So, why we need proteins? See proteins are the building blocks of life. They are important for growth and development in children, teens, they are important for pregnant women and we also need protein in our diet to help our body to repair cells and make new ones. So, proteins are quite important for humans and now the process by which a cell makes protein is called as translation. So, while making proteins they use the genetic information carried by the messenger RNA and we already saw that mRNA is made up by copying DNA. Therefore, the information which is carried by mRNA tells the cell how to link the amino acids together to form proteins. Now, they are guiding the amino acids because they are the basic structure of protein. That is a chain of amino acids forms protein and that is why we say that amino acids are the building blocks of protein. Now, these proteins they should be folded to become useful.  If you see this video you will understand the formation of protein and it will end with the folding of protein. I will start with what do we mean by folding of protein? So, now let us see what do we mean by folding of protein? See when the translation completes the flow of genetic information within the cell also completes and due to this translation the sequence of nucleotides in DNA has been now converted to the sequence of amino acids in a polypeptide chain. What is a polypeptide chain? See peptides are short chains of amino acids which are linked by peptide bonds. So, polypeptides are nothing but a polymer of amino acids, a group of amino acids. Now, this synthesis of polypeptide or the combination of polypeptide does not mean that a functional protein has been produced. It just means that the amino acids have been grouped together but they are not yet ready to become functional. So, what has to be done for the amino acids groups or the polypeptides to become useful? For this they must fold into distinct three-dimensional conformations and in some cases multiple polypeptide chains must assemble into a functional complex. Along with this many proteins also undergo further modifications which are critical for their functioning and these modifications are also important for correct localization of these proteins within the cells. So, that means protein folding is nothing but the physical process by which a protein chain is translated to its native three-dimensional structure. So, typically a folded conformation is when the protein becomes biologically functional. So, here you should note that there are also unfolded proteins or misfolded proteins. These proteins contribute to the pathology of many diseases. Now, this is where the molecular chaperones come in because the proper folding of proteins within the cells is mediated by the activities of other proteins. So, these proteins that facilitate the folding of other proteins are called as the molecular chaperones. Why the chaperone term is added here because see literally in English chaperone means a companion that is a person who accompanies or who looks after another person. So, here these molecular chaperones they look after the protein folding process or scientifically we can say that these chaperones act as catalyst that facilitate assembly without being part of the assembled complex. So, with this understanding now let us see the characteristics of these molecular chaperones. First of all we should note that these chaperones do not convey additional information that is required for folding of polypeptides into their correct three-dimensional conformations because the folding is determined solely by the sequence of amino acid. So, what these chaperones do they just catalyze protein folding by assisting the self-assembly process. In addition to this what they also do is that they bind and stabilize the unfolded or partially folded polypeptides. These are the ones that are intermediates along the pathway leading to the final correctly folded state. So, the molecular chaperones help in binding and stabilizing these unfolded polypeptides also. Now, if these chaperones are absent then the unfolded or partially folded polypeptide chains they would be unstable within the cell and what will happen is they will frequently fold incorrectly or they will be aggregating into insoluble complexes but since there are presence of chaperones they will bind to these unfolded polypeptides and stabilize them and thereby they will prevent incorrect folding or aggregation and it will also allow them to fold correctly. Now, in addition to this many of the proteins which are now known to function as molecular chaperones they were initially identified as heat shock proteins. See these heat shock proteins are a group of proteins which are produced in cells when the cells are subjected to elevated temperatures or other forms of environmental stress and the abbreviation of heat shock proteins is the term HSP. So, that means HSPs are specific proteins that are made when cells are briefly exposed to temperatures above their normal growth temperature. This is because when the cell is subjected to elevated temperature or stress at that time the protein begins to lose their original shapes that is they will lose their three-dimensional biologically functional shape and here the elevated temperature or stress is what is called as heat shock. So, to restore the proteins to their original form large quantities of chaperones are produced and some of the examples of these molecular chaperones are HSP 70, HSP 90. So, you can understand why there is HSP because these were the proteins which were initially identified as heat shock proteins. Now, here the number along with these HSP indicates the size in kilodaltons. Dalton is nothing but a unit of mass. So, these HSP 70, HSP 90 they have the ability to detect the temperature changes and stress. So, these are some of the characteristics of molecular chaperones. Now, let us see why we need them. See, we already saw why we need them. Now, we are just going to group them as points. Now, the first major significance of molecular chaperones is that they assist in protein folding. Now, secondly they also have an indirect significance which is they prevent diseases caused by improper folding of proteins. Here, let us take two examples to understand what this means. See, the alpha sinuclein protein which are present in neurons is wrongly folded in Parkinson's disease. That means when the alpha sinuclein protein they are wrongly folded or incorrectly folded then it leads to Parkinson's disease. And similarly, if we take crystallines these are the predominant structural proteins in the lens. When these are folded incorrectly then it leads to cataract in the eye. So, like this these improperly folded proteins or incorrectly folded proteins they lead to many diseases. Now, thirdly, chaperones also play a vital role in maintaining cellular hemostasis. See, hemostasis is a process which the living things use to actively maintain stable conditions that are necessary for survival. So, chaperones help in maintaining cellular hemostasis and it ensures that the cells are not subjected to stress. But if cells are subjected to any temperature or stress, it immediately restores the original shape of the proteins so that everything functions normally. In addition to this, these chaperones are also used as biomarkers of exposure to environmental stress in the fish. See, it is found that the industrial effluents, hydrocarbons, metals, pesticides, etc. they induce HSP in fish. So, that means if HSP is present in fish then the fish or the water body is subjected to these environmental stresses. So, these are some of the useful functions of molecular chaperones. But apart from all these functions it also has certain drawbacks. For example, cancerous cells accumulate mutations in protein that would normally suppress tumors. But the HSP 70 and HSP 90 they play the roles of villains here because they continue to fold the mutated proteins. So, they allow tumor progression. That means these HSPs or molecular chaperones, they do not differentiate between normal cell and the cancerous cell rather they help in folding of proteins in both these cells. So, if it happens in normal cell then it is fine for the human body. But if the same happens in a cancerous cell then that means it will lead to tumor progression. But here we should note that scientists have developed inhibitors of HSP 90. When we say inhibitors it refers to the substance which binds to these proteins and which decreases the activity of these molecules. And as per the scientists these inhibitors of HSP 90 they show much promise as anti-cancer agents. But even now no inhibitor has yet been approved for human use because the levels of inhibitors used for human purpose or to be effective in humans are too toxic for the human body. And that is why as of now no inhibitor has been approved for human use. So, that is all. In this discussion we understood what do we mean by molecular chaperones. We saw how proteins are formed and we saw some of the important functions of these molecular chaperones. And finally we also saw one of the drawbacks of molecular chaperones. So, with this discussion let us move on to the next one. Now this news article talks about the senses regarding two communities that are predominantly found in Arunachal Pradesh. These communities are the Chakmas and Hajongs. See a Chakmas and Hajongs census was conducted in the state of Arunachal Pradesh recently. So, one of the groups representing these communities has criticized that this census is a racial profiling operation. And therefore they have filed a complaint with the Prime Minister's office. So, in this discussion let us see about Chakmas and Hajongs and we will also see the issues faced by these communities. The syllabus relevant to this discussion is given here for your reference. First let us start with Chakmas. See Chakmas are a tribal community. They are one of the Buddhist communities in the Indian subcontinent. And anthropologically speaking Chakmas belong to the branch of Tibetan Burmese tribe and this Tibetan Burmese tribe originally belongs to the Mongolian race. Now let us see about the Chakmas based on two different time periods. Now one period is prior to the British rule in India and the other period is after the independence of India. So, first let us see about Chakmas prior to the British rule in India. See note that Chakmas at that time had an independent kingdom and this kingdom consisted of the present Chittagong hill tracks, the portion of Chittagong district of Bangladesh and it also included Dhaka trunk road and even some areas bordering the southern parts of Mizoram. This is the region as you can see here. This is the Chittagong hill track and the Chittagong district region in Bangladesh and these are the areas where we can find Chakmas. And during 1715 it is said that the Mughals had a war with Chakmas and the Mughals won in that war. So, Chakmas had to pay a tribute to the Mughals but after British East India company took over the administration of Bengal in the year 1757 this tribute was transferred to the British. Now what happened after British rule that is after India's independence? See it is said that on the day of India's independence Chakmas wished to join India but since the Chittagong hill tracks where the Chakmas lived was made part of Pakistan it could not happen. To be more specific we know that this region was included along with the eastern Pakistan which is now called as Bangladesh. But now why we talk about Chakmas most often? See the Chakmas are the people who were displaced when a dam was built on the Karnapuli river and this dam was called the Kaptaidam. See this Kaptaidam was completed in the early 1960s and it was built in the present day southeast Bangladesh. So during the construction of this dam many Chakmas they migrated to other regions of India and furthermore once when the country of Bangladesh was formed in 1971 at that time also tens of thousands of Chakmas migrated to India and when they migrated they were settled by the government in the Indian states of Mizoram, Manachal Pradesh and Tripura. So now let us see some of the characteristic features of this tribal community. See first Chakmas have their own language. This language is known as Changma Baach or Changma Hoda but now they speak a dialect of Bengali. This is because Chakmas have a centuries of contact with their neighboring Chittagongian population. Along with this they also use Bengali alphabet and next important fact you should know about Chakmas is that they officially follow the southern form of Buddhism that is the Theravada Buddhism which is also called as Hinayana Buddhism. Now if you look at the festival celebrated by Chakmas they also celebrate the Buddhist festival like Buddha Purnima and they also celebrate Biju festival which coincides with the Bengali New Year. As you know Biju is a festival that bids farewell to the previous year and welcomes the new year. Now next important fact about Chakmas is their occupation. See their major occupation is cultivation. They grow paddy, maize, cotton, sesame etc. and mainly they practice Jhum cultivation that is the slash and burn cultivation and they also know the art of lowland cultivation along with this. So these are few facts that you need to know about Chakmas. Now let us see about the Hajongs. See Hajongs are also a tribal group and they are native to the Indian subcontinent. They are located in the northeastern Indian states and they are also located in Bangladesh. And note that Hajongs belong to the Bodo Kachari people and they claim that their ancestral home was in the Hajjo area which is in the present day Assam now and then they speak the language called Hajong. And note that if we talk about the ethnicity then the majority of Hajongs are Hindus and as of now it is said that most of the Hajongs are settled in India. Therefore they celebrate some of the Hindu festivals like Durga Puja and Khamakya Puja and they also celebrate festivals like Biswa. See Biswa is a pre-Monson festival and they celebrate Kani Puja, Katka Puja etc. Just know the names of these pujas. Now what about their occupation? See like the Chakmas Hajongs are also cultivators but both of these communities follow different methods of cultivation. Predominantly Hajongs are rice farmers and it is said that Hajongs have brought the wetfield cultivation to the Garo hills and before this the people of Garo hills they used slash and burn methods of agriculture only but after the arrival of Hajongs they also started using wetfield cultivation. And note that Hajongs are spread across the states of Assam, Anushal Pradesh, Meghalaya and even other northeastern states and most importantly both of these communities that is Chakmas and Hajongs they have been listed as scheduled tribes in these states in our country. Take a note of this. Now let us get to the issues faced by Chakmas and Hajongs in India. See as you can understand that Chakmas are migrants and even a part of Hajongs who belong to Bangladesh they have also majorly settled in India now. So Hajongs are also migrants to some extent and therefore both of these communities face the issue of citizenship. Now you may ask that Government of India announced the Citizenship Amendment Act 2019 then why is there a issue of citizenship? It is because as you are well aware even though Citizenship Amendment Act provides a chance for the migrants but the areas in Anushal Pradesh is not covered under this act. It is because of the inner line permit. See you can recall that there is a clause in the Citizenship Amendment Act which says that the act doesn't apply to the tribal areas of Assam, Meghalaya, Mizoram or Tripura that are included in the schedule to the constitution and it doesn't even apply to the areas covered under the inter line which is also called as the inner line permit and we know that this inner line permit system prevails in the states of Anushal Pradesh, Nagaland and Mizoram. So that is why the citizenship issue of Chakmas and Hajongs will not be resolved by the Citizenship Amendment Act and that is why they are struggling to get their rights in India and they are losing on many benefits like they do not get access to the food grains under public distribution system. So like this they are facing many issues already and now there is a new issue which is mentioned in the news article. See since the census was conducted only for these two communities the group that represents this community it states that this census operation is nothing but racial profiling. So what is this racial profiling? See it refers to the process by which the law enforcement relies on generalizations or stereotyping based on race, color, descent, national origin or ethnic origin. So here the law enforcement does not focus on the objective such as evidence or individual's behavior rather just because they belong to a particular race, color or descent or ethnic origin they are subjected to certain actions by the law enforcement agencies and these actions include they are stopped while they travel to some places they are searched by the law enforcement agencies and they are even subjected to investigation just because they belong to that particular community and this is why racial profiling is a discriminatory process and because of this census operation now the people from Chakmas and Hajongs they fear that this will lead to racial profiling of Chakmas and Hajongs. So let us wait and see what happens regarding this issue whether the prime minister's office conducts an investigation and this matter or not. So that is all in this discussion we understood about two tribal groups in the northeastern states these are the tribal groups of Chakma and Hajong and we also saw the issues faced by both these communities. With this information let us get to the next discussion. Now look at this FAQ article it talks about the impacts of 5G technology in the aviation sector. See primarily this FAQ article discusses the recently released Air Worthiness Directive from the United States Federal Aviation Administration. So based on this directive the FAQ discusses how 5G equipment can impact the aviation industry's function and the implications of this directive to India and finally it also discusses what are the steps to be taken to ensure that 5G technology and aviation sector can coexist. So today we are going to discuss all these aspects the syllabus relevant to this discussion is given here for your reference. See first of all let us have a brief understanding about the 5G technology and its evolution. Now look at this table here here you can find the information regarding the evolution from 1G to 5G here what you should note is the bandwidth see bandwidth is nothing but is like a width of the river we know that if the width of the river is wider it can carry more water. So in a similar way if the bandwidth is higher it can carry more data. So similarly the 5G technology it has the capability to add more bandwidth and therefore it has the capacity to carry more data and it can have more functionality. Now in this table you can also see that the frequency range is also increasing with each generation. See when we use our phones our data is coded as digital signals in the radio waves that our phones are using. So if the frequency of the radio waves is higher then more data can be encoded and we saw that 5G technology has more frequency then more data can be encoded in it therefore it has more bandwidth that will help us to transmit more data. Now currently for the common use 5G will be rolled out in the C band if you see. So what is this C band it is a part of the radio wave spectrum where the frequency range is between 3.7 gigahertz to 4.2 gigahertz or we can say that it is between 3700 megahertz to 4200 megahertz. So this is the C band range but just now we saw in the table that 5G offers a frequency range from 3 gigahertz to 30 gigahertz but even still why mobile operators are choosing this 5G C band that lies in the frequency range of 3.7 to 4.2 gigahertz it is because C band has some advantages. See this C band frequency range for 5G provides rich opportunity for the operators. It delivers a balance between coverage and bandwidth which will benefit many verticals and applications. See this C band offers both good coverage and good throughput. So what this coverage means it refers to an area up to which the mobile tower can transmit the signal. On the other hand throughput means the actual amount of the data that is successfully sent or that is successfully received over the communication link. So this C band offers both good coverage and good throughput but in case of 5G if the frequency is higher than C band then it can offer very high throughput but the coverage will be very low. We need not know the technicality here just know that it can offer very high throughput but the coverage will be very low. Now on the other hand if the frequency is lower than the C band then it can offer very good coverage but very low throughput only and that is why the mobile operators are choosing the C band range. So these are the basics that you need to know about 5G C band and its advantages. Now why we are discussing these terminologies it is because recently the United States Federal Aviation Administration has released two airworthiness directives. See these directives were aimed at creating a framework as well as its aim was to gather more information about the potential impacts of 5G technology on crucial aviation safety equipment. As you know FAA is similar to our Directorate of Civil Aviation in India. So FAA aims to ensure safety and efficiency in the aviation industry in the United States of America and these airworthiness directives released by United States FAA are legally enforceable regulations and they are released to correct an unsafe condition in a product. So here point to be noted is that these airworthiness directives are legally enforceable. So now these directives are released for 5G technology because there is an unsafe condition in this 5G technology especially with respect to United States. See USA has already rolled out 5G technology and by January 2022 many mobile operators are planning to roll out 5G in the C band because as we saw it has many additional advantages. But now the Federal Aviation Administration is concerned that this 5G C band frequency is close to the frequency in certain important aircraft equipment and this is a cause for concern. So why this C band is a cause of concern for the aviation sector? Let us see that now. Now to understand that first you need to understand about altimeter. See all medium and large aircrafts have two types of altimeter. They are the pressure altimeter and the radio altimeter. Simply you just know that altimeters measure altitude. Now in case of pressure altimeter it measures the altitude of the aircraft in relation to the mean sea level. Now in case of radio altimeter it measures the height of the aircraft from the surface which is immediately below it. So here you can easily understand the difference between height and altitude. So height is measured by radio altimeter and the altitude is measured by pressure altimeter. Now this radio altimeter is very important instrument for precise approaches and landing of an aircraft. That means the radio altimeters play an important role in the safe operation of the aircrafts. Along with this they also provide valuable information for other equipment that help in predictive wind shear, that help in ground proximity warning system, traffic collision avoidance system and that help in autolanding. So this radio altimeter helps in other aircraft functions also and therefore for an aircraft to function properly a law depends on the efficient functioning of this radio altimeter. Now the issue is with respect to the frequency range of this radio altimeter. See this radio altimeter uses frequency range of 4.2 GHz to 4.4 GHz. But we already saw that the 5G C band it falls in the frequency range of 3.7 to 4.2 GHz That means there is a potential for 5G C band to interfere with the operation of the radio altimeter. But just now we saw that radio altimeter is important for safe functioning of the aircraft especially in the landing and therefore any disturbance caused to this internal radio altimeter caused either by the 5G equipments or other equipment transmitting in the frequency bands close to it can result in a disastrous effect and therefore it will affect various crucial systems that aid in the safe landing of the aircraft and the FAA directive which we saw is also concerned about this particular fact and that is why the directives have been given by the authority. So now let us see what are the takeaways from this directive to understand what is the issue between the 5G connectivity and aircraft functioning with respect to USA. See according to Captain A Ranganathan who is a former airline instructor pilot and aviation safety advisor there are four important points in this directive we are going to see only these four points see the first point is that the directive prohibits the use of autopilot mode in helicopters in the areas that have 5G connectivity that means auto hovering cannot be used in these areas what is this auto hovering see hovering is a state in which the aircraft is in a nearly motionless flight and this motionless flight is over a reference point at a constant altitude. So if hovering is done without an intervention of a pilot then it results in the auto hovering mode but since the 5G C band falls in the frequency range of 3.74.2 gigahertz it will interfere with the radio altimeters and therefore this auto hovering function cannot be used and that is why the directive prohibits the use of autopilot mode in the areas where there is 5G connectivity this is the first takeaway. Now the second point is that the directive also prohibits certain instruments such as instrument landing system approach then they require navigation performance operations and auto land. Let us not go into the technicality of these processes just know that prohibition of these will result in additional flight times and it will also lead to requirement of more fuel for each flight in addition to this it will also lead to the increase in the time gap between two flights because the flight times are increasing and therefore all this will lead to increase in flight delays. So this is the second point. Now the third and the most important thing is the issue of handheld mobile devices. See as you know majority of the air passengers they do not switch off their phones therefore this particular thing could pose extreme danger when the aircraft is flying in the vicinity of major airports where there is 5G connectivity. So even if you ban 5G towers around the airports but if the passenger switches on his or her phone when the aircraft is nearing the airport then there is a potential for the 5G to interfere with the radio altimeter in the aircraft therefore it will affect the safe landing. Now finally according to Captain Ranganathan for commercial aircrafts the risk is very limited to some specific circumstances such as low visibility landing but even in such case if there is a false input to the autopilot system due to the erroneous signals resulting from the 5GC band then it could also result in a crash of the aircraft. So this is also an issue. So these are the four takeaways from the FAA directive. Now does this directive have any implications on India or whether India should also follow the same kind of directive. It is not so because in India our government is planning to roll out 5G in the frequency band of 3.2 GHz to 3.6 GHz. But we saw that most of the aircrafts use radio altimeters with a frequency range of 4.2 to 4.4 GHz only. Therefore in case of India the potential for interference is very low and that is why as far as India is concerned we have no need for worry. So what is the solution to this problem? How 5G and aviation sector can coexist? How can we use 5G without affecting the aviation sector? See for this the first suggestion is that mobile operators can operate in certain frequencies within the C band itself. They should leave what is called a buffer between 5G signals and the frequencies that are used in aviation. For example, how India is planning to use? We are going to use 3.2 to 3.6 GHz. So similarly other countries can also use this frequency band rather than nearing that 4.2 GHz limit. So this will directly reduce the interference between 5G and radio altimeter. Now the second solution is that there needs to be a lot more research to realize the full implications of 5G on the radio altimeter and other aircraft systems. So we need research in this arena and then only we can take a well informed step. Now thirdly in case of India according to Captain Ranganathan he has suggested to the DGCA that it should order a band on 5G towers within the 15 nautical mile radius of any airfield. He is suggesting to ban 5G towers in this radius. It is because around many airports many densely packed urban areas are coming up. So if there is a 5G tower in this area and if there is any interference with the aircraft's radio it will lead to disastrous consequences. So that is why he is suggesting this. The same can also be used by USA in the current scenario. And the final suggestion is the easiest, safest and the cheapest one which is staying away from 5G as of now. Author is suggesting that we can stay away from 5G until there is further research regarding this issue. So that is all about 5G and its effect on aviation sector. In this discussion we understood what is 5G and what is the C band and what are its advantages. We saw how it will affect the functioning of aviation sector. So while discussing that we also saw about the altimeters especially the radio altimeter and why it is important and what are the problems associated with 5G and radio altimeter. And finally we saw some of the way forwards that could avoid the issue between 5G and altimeter and which could help in the coexistence of 5G along with aviation sector. So with these points in mind now let us move on to the next discussion. Our next discussion is going to be based on this news article which talks about the testing of pinaka extended range multi barrel rocket launcher system. It has been tested by the army. Now the significance of this testing is that this current testing used pinaka MK1ER rockets that were produced by an industry partner. Here ER stands for extended range. Now this technology of the pinaka MK1ER rockets were transferred by the DRDO to the industry partner. So after that the industry partner manufactured these rockets with DRDOs hand holding during the production and quality assurance period. So now coming to the pinaka extended range multi barrel rocket launcher system. This system was jointly designed by two laboratories of DRDO. These laboratories are Armament Research and Development Establishment that is ARDE in Pune and then High Energy Materials Research Laboratory which is HEMRL in Pune. So with these initial trials the initial phase of technology absorption of pinaka ER by the industry partner has been successfully completed. So this has made the industry partner ready for series of production of this rocket system. So this is the crux of this news article but today we are only going to see about pinaka extended range multi barrel rocket launcher system or simply the pinaka multi barrel rocket launcher. This is the image of this rocket launcher as you can see why this is named as multi barrel. You can see that this launcher is mounted on a truck. Now this truck is indigenously produced and this truck is called as TATRA or TATRA. Now this truck can carry a payload of 12 tons. Now it is equipped with an onboard generator which supplies the primary power for launcher operations. Now coming to the pinaka system it has two pods as you can see in this image and each of these pods contain six rockets. Now one of the specializations of these pinaka system is that this launcher is capable of firing in salvo mode within 40 to 48 seconds and through this it can utilize the area of 700 by 500 meters. See what is this salvo mode? It means that they can just hold on to the button and then it will simultaneously fire missiles. So within just 40 to 48 seconds all the missiles will be launched in this salvo mode. Now note that this launcher can be operated in four modes. These are the autonomous mode, standalone mode, remote mode and manual mode. Now in case of autonomous mode the fire control computer it independently controls the launcher. Now next is the standalone mode. Now in this the command is entered into the console by the operator. Now the next one is the remote mode. Now this one allows the operator to control the launcher from a distance of about 200 meters using a remote control unit. That is there is no need that they have to be present in this launcher. Now the final mode is the manual mode. Now this mode is adapted in the event of failure of microprocessor and loss of power. So that means in four different modes this launcher can be operated and that is why this makes this launcher widely adaptable and highly reliable. Now in this launcher various variants of rockets are used and these are called as the pinaka rockets. Here is the list of these pinaka rockets and you can see the range of these rockets. Just go through this. So now what is the application of this pinaka in the battlefield? Why is it important? See in the battlefield long range artillery systems like pinaka are used for attacking the adversary targets prior to the close quarter battles. That is this system tries to neutralize the target before it could come close and when the targets does come to close quarters then at that time small range artillery's then armored elements and the infantry are deployed to neutralize it. So that means the main aim of using a pinaka system is that it acts as a first line of defense and it protects the smaller artillery and infantry. So these are some of the few facts that you need to know about the pinaka launcher system and its significance. Now let us move on to the next discussion. See our last discussion is going to be based on this news article which talks about the birth anniversary of see Raju Kupalachari who was popularly known as Rajaji and this news article talks about his political career and the controversial education scheme that was introduced by him. So today what we are going to do is by taking this opportunity we are going to learn about see Raju Kupalachari from Pralams Point of View. So let us start the discussion. First note that he was born on 10th December 1878. He was born at Hozoor which is currently present in the Krishnagiri district of Tamil Nadu and as I already said he was popularly known as Rajaji. Now some of the important facts about him was that he was the first and the only Indian to be the Governor-General of India. He was also an ardent patriot, a pioneering social reformer, a sharp thinker, a profound scholar and also an author. Apart from all this he was also an eminent statesman and able administrator. His merits and traits elevated him to hold many highest positions such as he was the Governor-General in Free India as he already said then he was also Governor of Bengal then he also held the post of Premier of Madras Presidency and he was also the Chief Minister of Madras State and he also held the post of Minister for the Home Affairs of Indian Union. So keeping these points in mind let us see a timeline describing the major events in his political career. See in 1900s he began his career as a lawyer in Salem. Now by the 1905 the Swadeshi movement was developed due to the partition of Bengal. Now this incident changed the life of Rajaji because after this only the 1906 Congress session was held in Calcutta and Rajaji attended this session. He also attended the 1907 Surat Congress session and then in 1916 he started the Tamil Scientific Term Society. He also joined the Home Rule League and even started a branch of the league in Salem in Tamil Nadu. Then in the period 1917 to 1919 he served as the Chairman in Salem Municipal Council and during that period he brought such as he eradicated untouchability in the region, he promoted education among backward classes of people, he promoted education among the people from backward classes and he also promoted Samapandi which means intercaste dining and then in 1919 he became the prosecutor in Vedras High Court but after that he quit his lawyer profession when he met Gandhiji in Chennai. After meeting Gandhiji he even participated in the Raulat Satyagraha and then he participated in the non-cooperation movement in Chennai in 1920. Then after this he was sentenced to three months of imprisonment for attending a public meeting but after his release from this prison he even wrote a book called as Sirayil Tavam. He wrote this book in 1922 and then he was elected as a member of Congress Working Committee but then in 1922 itself Gandhiji was arrested so Rajaji was given an additional responsibility. This responsibility was publishing Gandhiji's journal Young India and then in the same year even attended the Gaya Congress session and followed the path of Gandhiji and from then on he played an important role in national politics also he even participated in the Vaikum Satyagraha that happened in 1924 and in the same year he started an ashram in a place called as Pudupalayam which is near Tiruchangoda in Tamil Nadu. See this ashram was constructed on the model of Gandhiji's Sabarmati ashram and he even named this ashram as Gandhi ashram. So remember this Gandhi ashram is in Pudupalayam near Tiruchangoda in Tamil Nadu. Now in the year 1929 Rajaji published a Tamil magazine called as Vimosanam from this ashram. See this journal dealt about prohibition of liquor and then in the 1930 he was elected as the president of Tamil Nadu Congress committee. So due to his accomplishments Gandhiji even praised Rajaji as my conscience keeper and then 1930 assumes an important role for Gandhiji because on March 12th Gandhiji began the famous Dandi march and he even broke the salt law on April 6th of 1930 and this was called the Salt Satyagraha if you remember. Now after this event immediately Rajaji along with 99 congress volunteers he started another Salt Satyagraha Yatra in Tamil Nadu. It was started on April 13th 1930 it was held from Tirucharapalli in Tamil Nadu to Vedaraniam. So as a part of this Yatra Rajaji took the Satyagrahis and broke the salt law and got arrested. Then after this in the year 1932 Rajaji became the acting president of All India Congress party and he even played a key role in the signing of Pune pact. So after his election to the All India Congress party Congress even contested in the Madras province election for the first time it happened in 1937 and in this election Congress won. So because of this Rajaji became the chief minister of Madras province in January 15th 1937. Now during his tenure as chief minister he passed many laws such as he passed the Agricultural Debt Relief Act to solve the problems of farmers then he formed a new committee under the then Revenue Minister to remove Zamindari system then he passed the temple entry authorization and indemnity act. This act gave legal right for the depressed class people to enter into temple and then during his rule only liquor prohibition was enacted for the first time in the Madras province. It was enacted in 1937 itself. So along with all these reforms and acts he also introduced Gandhiji's varda scheme of education in schools and this scheme was the one which triggered controversy regarding the education and then in the year 1938 he even made hindi as a compulsory second language in schools in Tamil Nadu. This was made compulsory from sixth to eighth standard. Actually this was the issue which paved the way for anti-hindi agitation in Tamil Nadu but then Rajaji and his cabinet resigned in 1939 because the British government made India to participate in the second world war without Indian leaders consultation. So after this 1939 came the important 1944 when Rajaji formed or formulated the Srirajagopalachari's formula which is in short called as CR formula. See this formula was primarily formulated to resolve the political deadlock between the All India Muslim League and the International Congress. So many proposals were part of this formula such as you know it is proposed that the Muslim League would join hands with the International Congress to demand independence from the British then mainly this formula also suggested that both the parties would cooperate and form a provisional government at the centre and then in case of partition joint agreements should be made between both the regions for safeguarding defence communications and commerce. So like this many proposals were part of this CR formula. So these are the few facts that you need to remember when you talk about Sriraju Gopalachari who was an active politician and a satyagrahi. So with this news article discussion we are moving to the next session of practice questions discussion. Let us take up this first question. It is a two statement question and this question is based on our molecular chaperones discussion. Let us see the first statement. Proteins that facilitate the folding of other proteins are called molecular chaperones. This statement is correct because this is the main function of molecular chaperones. Now the second statement molecular chaperones do not facilitate refolding of unfolded proteins caused by stress. This statement is incorrect because during discussion we saw that this is an indirect function of molecular chaperone. It also refolds the unfolded proteins which are caused by stress.
