All of the following are differences between RNA and DNA except A. RNA is a nucleic acid, DNA is not

B. RNA contains uracil, DNA does not

C. RNA contains ribose, DNA does not

D. RNA is single stranded, DNA is double stranded

C

The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose. These two are very similar in structure, with just one difference: the second carbon of ribose bears a hydroxyl group, while the equivalent carbon of deoxyribose has a hydrogen instead.
