A polypeptide has the following amino acid sequence: Met-Ala-Gln-Arg-Glu-Leu. This polypeptide was mutated to produce the following mutant sequence: Met-Ala-Gln-Thr-Gly-Thr-Ile-Thr. Which describes the MOST likely type of mutation that occurred?

Question

Quizplus · Accepted Answer

A frameshift mutation is likely because the mutant sequence is longer and has different amino acids after the mutation point, indicating a shift in the reading frame.
