The anticodon of a properly formed aminoacyl tRNA ensures that the correct amino acid is added with the reading of a specific codon during translation. The anticodon of the tRNA base pairs with the corresponding codon on the mRNA, and the amino acid attached to the tRNA is added to the growing polypeptide chain. Therefore, the correct pairing of the anticodon to the codon ensures that the proper amino acid is added to the polypeptide.
