Answer:
Frame-shift mutation
Explanation:
A frame-shift mutation can be simply defined as a kind of mutation that involves the insertion or removal of a distinct nucleotide, where the count of base pairs that are eliminated, is not possibly divisible by three. This divisibility of base pairs by three is significant as the cells present in the body is usually considered to be a gene which are found to be present in groups, comprising three distinct bases.
This type of mutation is caused mainly due to the induction of thymine dimer formation.
