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 is called a deoxyribose because it doesn’t have a hydroxyl group at the 2’ position. Instead it just has a hydrogen.

Detailed explanation-3: -The sugar in DNA is deoxyribose. The pyrimidines are cytosine (C) and thymine (T); the purines are guanine (G) and adenine (A). The bases are linked by hydrogen bonds such that A always pairs with T and G with C.
