Question: 1 / 400

What is the main difference between DNA and RNA?

DNA is double stranded, while RNA is single stranded

DNA contains thymine, while RNA contains uracil

DNA does not contain thymine and RNA does not contain uracil. Each nucleic acid has its own set of nitrogen bases, with DNA containing adenine, thymine, guanine, and cytosine, and RNA containing adenine, uracil, guanine, and cytosine. RNA does not contain thymine because uracil is used in its place for pairing with adenine. Therefore, option C is incorrect as well. Option D is also incorrect because DNA is involved in protein synthesis, providing a template for the formation of RNA which is then used to synthesize proteins. The main difference between DNA and RNA is the presence of thymine in DNA and uracil in RNA.
