Explanation:
Detailed explanation-1: -A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three. This is important because a cell reads a gene’s code in groups of three bases when making a protein.
Detailed explanation-2: -Insertions, deletions, and duplications can all be frameshift variants. Some regions of DNA contain short sequences of nucleotides that are repeated a number of times in a row.
Detailed explanation-3: -Insertion or deletion of three (or multiples of 3) nucleotides does not result in a frameshift mutation.
