Responses

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

DNA uses ribose while RNA uses deoxyribose as the sugar in the molecule’s backbone.
DNA uses ribose while RNA uses deoxyribose as the sugar in the molecule’s backbone.

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.

Answer 1

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

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

The other statements contain inaccuracies regarding the structure and composition of DNA and RNA. For instance, both DNA and RNA use phosphate groups to link nucleotides together, and DNA contains deoxyribose while RNA contains ribose. Additionally, DNA is typically double-stranded while RNA is usually single-stranded.
