PATHOLOGY

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 are mutations in which extra base pairs are inserted into a new place in the DNA.

Detailed explanation-3: -An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly.

Detailed explanation-4: -A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read.
