Explanation:
Detailed explanation-1: -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-2: -The sugar in DNA has 5 carbon atoms (labelled 1’-5’), and is called deoxy-ribose (hence the “Deoxy-ribo” in DNA). The term “deoxy” refers to the fact that there is no oxygen attached to the 2’ carbon atom.
Detailed explanation-3: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.
