6

Explanation:
Detailed explanation-1: -So it takes six nitrogen bases to code for one amino acid. So a codon codes for an amino acid and requires a total of six nitrogen bases.
Detailed explanation-2: -The three-letter nature of codons means that the four nucleotides found in mRNA-A, U, G, and C-can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
Detailed explanation-3: -A set of three bases makes up a codon. The messenger RNA contains many such codons, with a series of three bases followed by three more bases, and then three more bases, and so on.
