But not always: a silent mutation is a type of mutation in the coding region of a gene that doesn't actually change the amino acid sequence of the protein that is made. Below, learn how silent mutations work and why they're no big deal for an organism.
Point mutations are single base changes, that do not affect the reading frame; that is, the mutation only makes a single change in a single codon, and everything else is undisturbed. There are three types of point mutation:1  Silent Mutation.rameshift mutations alter the reading frame of the DNA. They come in two flavors: 1  Insertion: This mutation inserts a base pair (or more) into the DNA, shifting everything to the right (or left, depending on your point of view) by one base pair.
