A strain of E. coli carries a mutation that completely inactivates the enzyme encoded in the gene. Several revertants, mutants of the mutant with partly or fully restored activity, were selected, and the amino acid sequence of the enzyme was determined. The only differences found were at position 10 in the polypeptide chain.
Revertant 1 had Thr.
Revertant 2 had Glu.
Revertant 3 had Met.
Revertant 4 had Arg.
Assume that the initial mutation itself, as well as each revertant, resulted from a single nucleotide substitution.
a. What amino acid is present at position 10 in the mutant protein?
b. What codon in the mRNA would encode this amino acid?
