Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Can you sum up what these former survivor players said about meeting Jeff Probst in a few sentences?

"Survivor: Island of the Idols" player Elaine Stott said that although she was nervous before she met the "Survivor" host, the fact that she was sitting in front of producers and Probst "didn't really matter to me." 

"I told dirty jokes, I flirted, I cussed, I made fun of myself. That's just how I am in general," Stott told Insider. "... I said, 'Jeff, you're just a man, you put your britches on just like I do.'" 

Freberg added that the interviewers just "tell you to start talking" instead of asking direct questions, and Probst sits there "trying to size you up and trying to be intimidating."

"You just need something funny to say, so I made it up on the spot," Freberg recalled. "... I look at Jeff and I go, 'My grandma's gonna freak the f--- out when she finds out I met you.'"

Freberg added that his joke "got a big laugh," so he was "off to a good start after that."
Response: When Elaine Stott was in front of Probst and producers her nervousness went away. Freberg said the producers didn't ask questions and he was told to just start talking. Jeff sized them up, but Freeberg came up with a funny joke from the start and that put them on good terms for the rest of the interview.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the main points from the following passage about the structure and function of DNA (deoxyribonucleic acid):

DNA, or deoxyribonucleic acid, is the hereditary material found in the nucleus of cells. It contains the genetic instructions for the development and function of living organisms. The structure of DNA was discovered in 1953 by James Watson and Francis Crick.  

DNA is composed of two strands that wind around each other to form a double helix shape. Each strand is made up of four different types of nucleotides - adenine (A), cytosine (C), guanine (G), and thymine (T). The nucleotides are held together by phosphate and sugar molecules, forming the sugar-phosphate backbone of each strand.

The two strands are held together by hydrogen bonds between the base pairs A-T and C-G. This complementary base pairing is a key feature of the DNA structure. The sequence of these base pairs encodes the genetic information required for constructing proteins.

During cell division, DNA replicates itself by separating the two strands and using each as a template to build a new complementary strand. This ensures genetic information is passed on accurately.

DNA (deoxyribonucleic acid) is the hereditary material containing genetic instructions. Its structure, discovered in 1953, is a double helix formed by two strands of nucleotides (A, C, G, T) joined by phosphate-sugar backbones. A=T and C=G base pairs join the strands via hydrogen bonds. The base sequence encodes information for protein synthesis. DNA replicates by separating strands which act as templates for new complementary strands, accurately transmitting genes.
