Detailed explanation-1: -Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation. RNA is synthesized from DNA by an enzyme known as RNA polymerase during a process called transcription.

Detailed explanation-2: -ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.

Detailed explanation-3: -While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5).

Detailed explanation-4: -Explanation: Ribose is a 5C sugar found in RNA, hence the name Ribose Nucleic Acid.

Detailed explanation-5: -The five-carbon sugar, which is present in the ribonucleotide unit of the RNA, is ribose sugar.
