What sugar is present in RNA?

Explanation:
The sugar present in RNA is ribose. RNA nucleotides are built from ribose, a five-carbon sugar, plus a phosphate and a nitrogenous base. A key difference from DNA is that ribose has a hydroxyl group at the 2' carbon, whereas DNA uses deoxyribose, which lacks that 2' hydroxyl. Glucose and fructose are other sugars and are not used as the backbone sugar in nucleic acids.
