Explanation:
Detailed explanation-1: -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. A DNA sequence is a chain of many smaller molecules called nucleotides.
Detailed explanation-2: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
Detailed explanation-3: -Types of Mutations There are three types of DNA Mutations: base substitutions, deletions and insertions.
Detailed explanation-4: -Two frameshift mutations in the CFTR genes cause cystic fibrosis (one involves the insertion of two nucleotides, and the other involves the deletion of one nucleotide).
