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 is deoxyribose. The pyrimidines are cytosine (C) and thymine (T); the purines are guanine (G) and adenine (A).
Detailed explanation-3: -Deoxyribose is the sugar component of DNA, just as ribose serves that role in RNA (ribonucleic acid). Alternating with phosphate bases, deoxyribose forms the backbone of the DNA, binding to the nitrogenous bases adenine, thymine, guanine, and cytosine.
