Detailed explanation-1: -Amino acids and proteins are similar to the nucleotides and nucleic acids. Just as proteins are made up of numbers of amino acids, similarly nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides.

Detailed explanation-2: -Amino acids are to proteins as nucleotides are to nucleic acids. Amino acids are the monomers of the polypeptide chain that are synthesised during the translation process from the mRNA.

Detailed explanation-3: -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-4: -Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

Detailed explanation-5: -Definition. 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).
