Answer:A codon can be found on the mRNA.
Explanation: Even though the model is not shown, translation is a process in which the genetic message in an mRNA molecule is converted into an amino acid sequence of a protein. A codon is a three nucleotide sequence on a mRNA that specifies a particular amino acid. During translation, the mRNA is passed through the ribosome three nucleotides at a time where with the help of a transfer RNA, the corresponding amino acid residue is fetched from the cytosol and attached to the growing polypeptide chain.
