Detailed explanation-1: -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: -Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA).
Detailed explanation-4: -During evolution ribose was selected as the exclusive sugar component of nucleic acids. The selection is explained by using molecular models and by eliminating most of the other common sugars by looking at their chemical structure and envisioning how they would fit in a nucleic acid model.
Detailed explanation-5: -Ribose sugar is found in the RNA of living organisms. RNA is responsible for coding and decoding genetic information.
