Question

Quizplus · Accepted Answer

Ribose and deoxyribose are both present in nucleic acids. The primary difference between them is that ribose has one more oxygen atom than deoxyribose. This means that deoxyribose is missing one of the hydroxyl groups (-OH) found in ribose. Additionally, ribose is present in RNA, while deoxyribose is found in DNA.
