An example of a suppressor mutation would be
A) An intragenic mutation that restores the inactive protein's structure

Question

Quizplus · Accepted Answer

In this case, the intragenic suppressor mutation restores the protein's structure, thereby rescuing its function. Option B and C do not describe suppressor mutations, and D is too broad and does not specify the type of mutation.
