Biology

Lilit [14]3 years ago
6 0

Answer:

64

Explanation:

A codon is a group of three nucleotide sequence in a mRNA that specifies a particular amino acid acid. There are only four nucleotides composed of the four nitrogenous bases viz: Adenine, Guanine, Cytosine and Thymine/Uracil.

A codon is composed of only three of these nucleotide bases at a time. Hence, considering the number of nucleotide bases that can make up one codon and the 4 nucleotide bases, there can only be 4^3 = 64 combinations of the four nucleotides. This means that there are 64 possible codons.
