A strain of E. coli contains a mutant tRNALeu. Instead of recognizing the codon 5' CUG 3', as it does in nonmutant cells, the mutant tRNA recognizes the codon 5'GUG3'. A missense mutation of another gene, bug, affecting amino acid number 28 of the Bug protein, is suppressed in cells with the mutant tRNALeu.

What amino acid would be inserted at postion 28 of the mutant polypeptide chain if it is not suppressed?
