Each position of a codon can be occupied by one of four nucleotides. What is the minimum number of nucleotides per codon necessary to specify all 20 of the amino acids that are typical of eukaryotic proteins?

What will be an ideal response?


The minimum number of nucleotides per codon (assuming four total nucleotides) necessary to specify all 20 amino acids would be three. One-nucleotide codons could specify only four amino acids, and two-nucleotide codons could specify only 16 amino acids. Three-nucleotide codons can specify 64 amino acids (ignoring stop codons).
