Answer
3 nucleotides make up a codon.
Explanation
A Nucleotide is that the basic building block of nucleic acids. RNA and DNA are polymers fabricated from long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) connected to a phosphate cluster and a nitrogen-containing base. The bases utilized in DNA area unit adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
The nucleotide triplet that encodes an amino acid is termed a codon. every cluster of 3 nucleotides encodes one amino acid. Since there are sixty-four combos of four nucleotides taken 3 at a time and only twenty amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
