Detailed explanation-1: -Mutagenesis is the process by which an organism’s deoxyribonucleic acids (DNA) change, resulting in a gene mutation. A mutation is a permanent and heritable change in genetic material, which can result in altered protein function and phenotypic changes.
Detailed explanation-2: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
Detailed explanation-3: -Vector containing DNA sequence similar to the gene to be modified is introduced to the cell, and by a process of recombination replaces the target gene in the chromosome. This method can be used to introduce a mutation or knock out a gene, for example as used in the production of knockout mice.
Detailed explanation-4: -Types of Mutations There are three types of DNA Mutations: base substitutions, deletions and insertions.
