RNA contains the sugar ______.

Explanation:
RNA uses a five-carbon sugar called ribose in its backbone. This sugar is part of each ribonucleotide, along with a phosphate group and a nitrogenous base. The key difference from DNA is that DNA uses deoxyribose, which lacks the hydroxyl group on the 2' carbon, making DNA more chemically stable. Glucose and fructose are simple sugars used in metabolism, not components of nucleic acids. That’s why RNA contains ribose.
