Explanation:
Detailed explanation-1: -Answer and Explanation: Nucleotides are formed from d) a nitrogenous base (may be adenine, cytosine, guanine, thymine or uracil), a pentose sugar (ribose or deoxyribose), and 1 or more phosphate groups.
Detailed explanation-2: -An amino acid is a monomer of a protein molecule while a nucleotide is a monomer of a nucleic acid. Therefore, this is the key difference between amino acid and nucleotide. Moreover, the amino acid has C, H, N, O and S atoms while nucleotide has C, H, N, O and P atoms.
Detailed explanation-3: -Explanation: A nucleotide is composed of a base, a sugar and a phosphate.
