What is what sugar is found in dna?

The sugar found in DNA is deoxyribose. It's a pentose sugar (a five-carbon sugar), meaning it has five carbon atoms in its ring structure. The "deoxy" prefix indicates that it lacks an oxygen atom on the 2' carbon compared to ribose, the sugar found in RNA. This seemingly small difference is crucial to DNA's structure and function. The absence of the hydroxyl group at the 2' position makes DNA more stable than RNA, which is important for long-term storage of genetic information.
