Explanation:
Detailed explanation-1: -(FRAYM-shift myoo-TAY-shun) An insertion or deletion involving a number of base pairs that is not a multiple of three, which consequently disrupts the triplet reading frame of a DNA sequence.
Detailed explanation-2: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
Detailed explanation-3: -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).
Detailed explanation-4: -A substitution mutation changes the codon CCC to CCA, both of these codons code for Proline.
