Detailed explanation-1: -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-2: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules. Note the absence of the hydroxyl (-OH) group on the 2’ carbon in the deoxy-ribose sugar in DNA as compared with the ribose sugar in RNA.
Detailed explanation-3: -Deoxyribose is a five-carbon sugar found in DNA. It is the nucleotide’s central molecule.
Detailed explanation-4: -deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.
