Answer:
64.
Explanation:
It is 64 because there are 20 amino acids with four bases ( A,T,C and G).
and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid
Therefore the number of codons is 4×4×4= 64.
