Some mutations do not affect the amino acid sequence of the protein produced using the mutated gene. How can the correct amino acid be incorporated into the protein despite a mutation in the gene sequence? The codon containing the mutation may still specify the original amino acid. Some mutations are detected and corrected as the pre-mRNA is being synthesized. Only the first of the three nucleotides in a codon is used to determine the correct amino acid. Enzymes correct many of the mistakes in the amino acid sequence after the protein is made.

A gene encodes a protein with the following amino acid sequence: $$\mathrm{Met-Lys-Ser-Pro-Ala-Thr-Pro}$$ A nonsense mutation caused by a single-base-pair substitution occurs in this gene, resulting in a protein with the amino acid sequence Met-Lys. An intergenic suppressor mutation allows the gene to produce the fulllength protein. With the original mutation and the intergenic suppressor present, the gene now produces a protein with the following amino acid sequence: $$\mathrm{Met-Lys-Cys-Pro-Ala-Thr-Pro}$$ Give the location and nature of the original mutation and of the intergenic suppressor.
