Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA). 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. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
Detailed explanation-2: -Nucleotides are the building blocks, i.e., the repeat units or monomers of nucleic acids. Nucleotides are composed of three sub-units: a 5-carbon carbohydrate, a base that is an aromatic compound containing nitrogen, and.
Detailed explanation-3: -The building blocks of proteins are amino acids. The building blocks of proteins are amino acids. Nucleotides consisting of sugar deoxyribose, one phosphate group, and one of four nitrogen bases are building blocks of DNA; adenine (A), guanine (G), cytosine (C), and thymine (T).
