RNA contains which sugar and is typically what in structure?

Explanation:
RNA uses ribose as its sugar, which has a hydroxyl group at the 2' position. This distinguishes RNA from DNA, which contains deoxyribose. Because RNA typically exists as a single polynucleotide chain, it is usually single-stranded, though it can fold back on itself to form local double-stranded regions through intramolecular base pairing. The overall structure is not a long, uniform double helix like DNA. Therefore, describing RNA as containing ribose sugar and being typically single-stranded best fits its common properties.
