a) Suppressor
b) Reversion
c) Inducer
d) Enhancer

Answer 1

The term for a second mutation in a different gene that restores protein function is a suppressor.

Step-by-step explanation:

The restoration of protein function by a second mutation in a different gene is known as a suppressor. When an initial mutation leads to a loss of function in a protein, occasionally, a second mutation can occur in a different part of the DNA that somehow compensates or corrects the dysfunctional protein, thereby restoring its function. This second mutation doesn't reverse the original mutation (which would be called a reversion), but rather, it bypasses or fixes the problem in a different way, often involving a different gene or genetic pathway.
