What sugar is found in DNA?

Explanation:
DNA uses a five-carbon sugar called deoxyrose, specifically deoxyribose, in its backbone. The term deoxy indicates it is missing an oxygen at the 2' position, unlike ribose in RNA which has a 2' hydroxyl. That single difference makes DNA chemically more stable, helping preserve genetic information over time. Glucose and fructose are hexose sugars used mainly for energy and are not components of DNA, while ribose is the sugar found in RNA, not DNA.
