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: In a few sentences, explain investing using this:

Investing
Investing involves purchasing assets, usually stocks and bonds, to earn a return on the money invested. Investing aims to increase an individual's wealth beyond the amount they invested. Investing does come with risks, as not all assets appreciate and can incur a loss.

Investing can be difficult for those unfamiliar with it—it helps to dedicate some time to gain an understanding through readings and studying. If you don't have time, you might benefit from hiring a professional to help you invest your money.
Response: Investing is the buying of assets, such as stocks and bonds, to increase money over time. It comes with risks, but taking time to understand the process or hiring a professional can make it less difficult.

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.

Explain the process of DNA replication in a few sentences.
user
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. It occurs during cell division, ensuring each new cell receives an exact copy of the DNA. The double helix unwinds, and each strand serves as a template for the formation of a new complementary strand.
