Question

Suppressor mutations can be:

A. intergenic.
B. intragenic.
C. reverse.
D. A and B.
E. All of the above.

Answer 1

Suppressor mutations can be intergenic, intragenic, or reverse, meaning all options are correct.

Step-by-step explanation:

Suppressor mutations can indeed be intergenic, which occur in a different gene than the one containing the initial mutation, or intragenic, which occur in the same gene as the initial mutation but restore function in a different way, such as through a different amino acid change. They can also be considered reverse if they revert the mutation back to the original state. Therefore, the correct answer to the question, 'Suppressor mutations can be:', is E. All of the above.
