Deoxyribose vs. Ribose: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Deoxyribose, a sugar in DNA, lacks an oxygen atom at the 2' position unlike ribose, a sugar in RNA, which contains an oxygen atom at the same position.
Key Differences
Deoxyribose, found in DNA, is a five-carbon sugar missing an oxygen atom on its second carbon. Conversely, ribose, the sugar component of RNA, has an oxygen atom attached to every carbon.
