BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Each nucleotide consists of a phosphate group, a nitrogenous base-adenine (A), thymine (T), cytosine (C), or guanine (G)-and deoxyribose. DNA’s sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring. Four carbons plus an oxygen are part of the five-sided ring.

Detailed explanation-2: -Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.

Detailed explanation-3: -One nucleotide of a DNA molecule consists of a phosphate group, a pentose (five-carbon) sugar called deoxyribose, and a nitrogenous base (adenine, thymine, guanine, cytosine).

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.

Detailed explanation-5: -Deoxyribose is a five-carbon sugar found in DNA. It is the nucleotide’s central molecule. Thus, Deoxyribose is the five-carbon sugar found in DNA.
