Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -The deoxyribose sugar of the DNA backbone has 5 carbons and 3 oxygens. The carbon atoms are numbered 1’, 2’, 3’, 4’, and 5’ to distinguish from the numbering of the atoms of the purine and pyrmidine rings.
