# DNA & RNA

## Introduction

You may be familiar with the terms DNA and RNA, but you may be surprised when you find out more about their characteristics. This chapter focuses on explaining the main concepts of DNA and RNA, as well as how they correlate to other processes.

## Nucleic Acids

To start, read [this article](https://www.khanacademy.org/science/biology/macromolecules/nucleic-acids/a/nucleic-acids?modal=1) to get acquainted with the main characteristics of nucleic acids, and come back afterward.

Now that you have a better understanding of nucleic acids, DNA, and RNA, broaden your knowledge in these topics by watching the following videos (make sure to watch them fully, as this is one of the most fundamental topics in the course).

Finally, be sure to read [this article about the molecular mechanism of DNA replication](https://www.khanacademy.org/science/biology/dna-as-the-genetic-material/dna-replication/a/molecular-mechanism-of-dna-replication), as well as [this one about the mode of DNA replication](https://www.khanacademy.org/science/biology/dna-as-the-genetic-material/dna-replication/a/mode-of-dna-replication-meselson-stahl-experiment), and return here afterward.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.abi.am/abi-omicss-guide-2021/week-1/molecular-biology/dna-and-rna.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
