Explanation:
Detailed explanation-1: -Hence the three components of a nucleotide are nitrogenous base, a pentose sugar, and phosphate.
Detailed explanation-2: -A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
Detailed explanation-3: -Deoxyribonucleic acid (DNA) is a long, double-stranded, helical molecule composed of building blocks called deoxyribonucleotides. A deoxyribonucleotide is composed of 3 parts: a molecule of the 5-carbon sugar deoxyribose, a nitrogenous base, and a phosphate group.
