DNA has a double helix structure, while RNA is a single stranded structure.

DNA contains ribose, while RNA contains deoxyribose.
DNA contains ribose, while RNA contains deoxyribose.

DNA has a linear structure, while RNA is double-stranded.
DNA has a linear structure, while RNA is double-stranded.

DNA contains adenine, guanine, cytosine and uracil, while RNA contains adenine, guanine, cytosine, and thymine.

Answer 1

The correct response describing the differences between the structures of DNA and RNA is:

DNA has a double helix structure, while RNA is a single stranded structure.

To clarify further, DNA contains deoxyribose sugar, while RNA contains ribose sugar. Additionally, DNA has thymine, while RNA has uracil instead. The statement regarding linear structure in DNA and double-stranded RNA is incorrect because RNA is typically single-stranded, not double-stranded.

So, the main differences are:

1. Structure: DNA is double-stranded (double helix), whereas RNA is single-stranded.
2. Sugar: DNA contains deoxyribose, while RNA contains ribose.
3. Nitrogenous Bases: DNA contains thymine; RNA contains uracil instead of thymine.
