A gene with the original sequence of ATGTT-TACT underwent substitution mutation to form ATATT-TACT after a few generations. TACT is a part of a muscle protein encoding region, and ATGTT codes for a digestive enzyme. What will be the effect of this mutation?

Victoria Gardner · Answer 1

The production of the digestive enzymes will be affected by the mutation.

Explanation:

As the coding sequence for the digestive enzyme has been changed from ATGTT region to ATATT, it will affect the production of the digestive enzyme. As the coding sequence for muscle protein i. e TACT has not been changed after mutation, hence it will continue to produce the muscle protein normally and the mutation will not have any effect on this protein.

This kind of mutation in which one of the bases gets changed is known as a substitution mutation.
