Explanation of Chemical Components of DNA The bases themselves are classified into two groups known as purines (adenine and guanine) and pyrimidines (cytosine and thymine). Albeit slightly on a different note, RNA (RiboNucleic Acid) incorporates a fifth base known as uracil (U) which takes the place of thymine within the functional RNA structure.

- In DNA and RNA nucleotides, as well as other important biological molecules, a pyrimidine is one of three nitrogenous organic bases. Each pyrimidine is made up of a single ring containing nitrogen. The two pyrimidines in DNA are cytosine and thymine; the two pyrimidines in RNA are cytosine and uracil.

Explain the components of DNA and explain its functional relationship to RNA and protein? DNA or Deoxyhydro-Neucleic Acid is composed of base pairs, nitrogen and phosphates. The nitrogen and phosphates form the backbone of the DNA structure and take the shape of a double helix with the base pairs on the inside and the backbone on the outside.here are four base pairs, adenine, guanine, cytosine, and thymine (represented by the letters A, T, C, and G) A bonds with T, C bonds with G via hydrogen bonding. A cannot bond to either C or G. This is a major function of the structure of DNA in protecting the information it contains.

Temperature Controls of Potentially Hazardous Food When a source of heat is available, hold hot foods at 135 degrees Fahrenheit or higher and check the temperature every four hours. If the temperature of the food at four hours is less than 135 degrees Fahrenheit, the food must be discarded. It is permissible to hold hot food without temperature controls for up to four hours if the following conditions are met: Food must be held at 135 degrees Fahrenheit or higher before the food is removed from the temperature control.

Concept 1 Review The nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate. Cytosine and thymine are pyrimidine bases, while adenine and guanine are purine bases. The sugar and the base together are called a nucleoside.

Why Do We Need DNA? DNA consists of a double helix or a double chain of nucleic acids that are coiled around like a spiral staircase. The four subunits, or nucleotides of human DNA are adenine, guanine, thymine and cytosine. These form genes that are the basis of various characteristics or physical traits.

DNA The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase —either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group.ranscription is carried out by a DNA-dependent RNA polymerase that copies the sequence of a DNA strand into RNA. To begin transcribing a gene, the RNA polymerase binds to a sequence of DNA called a promoter and separates the DNA strands.

What compounds are the building blocks of DNA macromolecules? Nitrogenous bases, phosphate and pentose sugar. Nitrogenous bases, phosphate and pentose sugar are building blocks of DNA. The nitrogenous bases are purines and pyramidines. The purines are adenine guanine, while the pyramidines are cytosine and thymine. The pentose sugar, phosphate and one nitrogenous base form a long chain called polynucleotide chain.

- The largest and most clearly visible of the cell's constituents is the nucleus. Within the nucleus, DNA molecules, the cell's genetic machinery, are stored, repaired, transcribed and eventually replicated. Around the outside of the nucleus is an envelope consisting of two layers of membrane.

- able. Researchers already knew that DNA was a relatively simple molecule. It seemed to consist of an un-remarkable chain of phosphates and sugars, in some way attached to a set of ring-shaped molecules called nitrogenous bases. These bases come in four “flavors”: adenine (A), thymine (T), cytosine (C), and guanine (G) (Fig. 4).

extracting DNA Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders, produce DNA fingerprints of individuals, and even create genetically engineered organisms that can produce beneficial products such as insulin, antibiotics, and hormones.o extract DNA from cells. Materials: Blender, split peas, salt, detergent, water, measuring cup and spoons, strainer, meat tenderizer, alcohol, test tube, glass stirring rod. Procedure: 1  First, you need to find something that contains DNA such as split peas, fresh spinach, chicken liver, onion, or broccoli.

Nucleotide In DNA, the purine bases include adenine and guanine while the pyrimidine bases are thymine and cytosine. RNA includes adenine, guanine, cytosine, and uracil in stead of thymine (thymine is produced by adding a methyl to uracil). Aside from serving as precursors of nucleic acids, nucleotides also serve as important cofactors in cellular signaling and metabolism.

What is DNA? Each nucleotide contains a sugar and a phosphate molecule, which make up the ‘backbone’ of DNA, and, one of four organic bases. The bases are adenine (A), guanine (G), cytosine (C) and thymine (T).

What is a nucleoid? Experimental evidence suggests that the nucleoid is largely composed of DNA, about 60%, with a small amount of RNA and protein. The latter two constituents are likely to be mainly messenger RNA and the transcription factor proteins found regulating the bacterial genome.

Describe the relationships between cell, nucleus, chromosome, DNA, gene? Gene is a small fragment of DNA, which contain information for the synthesis of protein. Chromosome contain DNA and basic proteins known as histones. DNA is nucleic acid containing sugar, nucleotide base and phosphate. Chromosome present in the nucleolus of the nucleus. Nucleus is present in the cell.. The gene is made up of the DNA molecule and is the basic unit of protein genesis. 3. The chromosome is a long chain of gene sequences which are themselves made up of DNA molecules.

- Part I-Components of DNA-DNA is made of three types of compounds. 1  Phosphate groups which are negatively charged and give DNA molecules a negative charge.note that the carbons in deoxyribose are numbered). 2. DNA is double stranded (ds), meaning there are two of the above strands together. Try to assemble a ds DNA molecule with sugar phosphate backbones on the outside, and nitrogen bases on the inside.

What is DNA? It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

DNA, Genes and Chromosomes The nucleus of each cell in our bodies contains approximately 1.8 metres of DNA in total, although each strand is less than one millionth of a centimetre thick. This DNA is tightly packed into structures called chromosomes, which consist of long chains of DNA and associated proteins. In eukaryotes, DNA molecules are tightly wound around proteins - called histone proteins - which provide structural support and play a role in controlling the activities of the genes.

DNA The complementary nitrogenous bases are divided into two groups, pyrimidines and purines. In a DNA molecule, the pyrimidines are thymine and cytosine, the purines are adenine and guanine. DNA stores biological information. The DNA backbone is resistant to cleavage, and both strands of the double-stranded structure store the same biological information.
