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.
The two types of single gene mutations are point mutation, where a single point in the DNA sequence is affected, and FRAMESHIFT MUTATION, where a single gene or nitrogen base is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.he two types of single gene mutations are point mutation, where a single point in the DNA sequence is affected, and FRAMESHIFT MUTATION, where a single gene or nitrogen base is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.
