Question: 1. what is the difference between ribose and deoxyribose?
Answer: Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). ... In deoxyribose, carbon atom #2 carries a hyrogen atom instead of a hydroxyl group.
