DNA is a single-stranded molecule whereas RNA is a double-stranded molecule in cells.
DNA is a single-stranded molecule whereas RNA is a double-stranded molecule in cells.

Adenine binds with the nitrogen base thymine in DNA while it binds with uracil in RNA.
Adenine binds with the nitrogen base thymine in DNA while it binds with uracil in RNA.

DNA uses phosphate groups to link nucleotides together whereas RNA uses ketone groups.

Answer 1

The correct statement that describes a difference between RNA and DNA is:

Adenine binds with the nitrogen base thymine in DNA while it binds with uracil in RNA.

To clarify, DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA is typically double-stranded, and RNA is usually single-stranded. Additionally, in DNA, adenine pairs with thymine and in RNA, adenine pairs with uracil. The last statement about phosphate groups and ketone groups is incorrect; both DNA and RNA use phosphate groups to link nucleotides together.
