There are 64 codons that is contained in the mRNA.
<h2>Explanation </h2>
The codons contained by the mRNA produced by DNA consist of three nucleotides and a single amino acid. The mRNA uses uracil nucleotide as a base. The genetic code is known as a codon. There are almost sixty four codons but three of which do not code for amino acids. The codons found in the base pairs of strands of mRNA during the process of translation.
