Explanation of Solution
h.
To determine:
The term that describes “often causes a frameshift”.
Answer to Problem 16SA
Correct answer:
Often causes a frameshift: Deletion.
Explanation of Solution
Mutation is defined as the changes in the genetic material of an organism. There are different types of mutation, such as frameshift mutation and so on. Generally, mutation occurs either due to insertion or deletion in the genetic material. Frameshift is caused due to the deletion of a
