Detailed explanation-1: -Types of Point Mutations. We are going to focus on the following point mutations: frameshift, silent, nonsense, and missense. Let’s start with a frameshift mutation, where there’s an insertion or deletion of one or more bases.
Detailed explanation-2: -Types of Mutations There are three types of DNA Mutations: base substitutions, deletions and insertions.
Detailed explanation-3: -A point mutation is a one nucleotide substitution in the DNA sequence. There are three types of point mutations. Silent mutations, missense mutations and nonsense mutations.
Detailed explanation-4: -Chromosomal mutation examples include chromosome deletion, duplication, inversion, and translation. These are known to cause different kinds of genetic and chromosomal mutation diseases.
