Question

Quizplus · Accepted Answer

The sugar in DNA (deoxyribose) contains one less oxygen atom compared to the sugar in RNA (ribose). Deoxyribose has a hydrogen atom bonded to the 2' carbon atom, whereas ribose has a hydroxyl (OH) group bonded to the same carbon atom. This small difference affects the stability and structure of the nucleic acid molecule.
