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: Sum up what the following article says about why Americans are experiencing a “friendship recession.”

So it is alarming that Americans are experiencing a “friendship recession.”

The startling decline of friendship
Modern living is tough on friendship.Unlike our ancestors who knew everyone in their tribe, most people now live in cities where the default is anonymity. As children and young adults, school may provide a social community. Indeed, the number of friends people have peaks around age 25, but then substantially drops around age 30, when work and the nuclear family take over.

Americans, especially those who are highly educated and high-earning, work longer hours and are more likely to move for work than ever before. Parents also spend twice as much time with their children than previous generations. This saps the ability to maintain close friendships.

The last decade has seen a startling further fall in the number and quality of friendships.
Response: There are many reasons why Americans are seeing a decline in the number and quality of friendships over the last decade. A couple of these reasons may be attributed to many Americans working longer hours and parents spending more time with their children than in prior generations.

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 about the structure and function of DNA (deoxyribonucleic acid) from the following text:

DNA (deoxyribonucleic acid) is a complex molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms. It is composed of two long strands of nucleotides twisted into a double helix structure. Each nucleotide consists of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). The specific sequence of these bases encodes the genetic information, which is used to synthesize proteins, the building blocks of cells. DNA is found in the nucleus of every cell and is organized into structures called chromosomes. During cell division, the DNA is replicated and passed on to daughter cells, ensuring the continuity of genetic information. DNA also has the ability to repair itself and to undergo mutations, which can lead to variations within a species. The structure and function of DNA were first described by James Watson and Francis Crick in 1953, and this discovery laid the foundation for modern genetics and molecular biology.
