Now, the final type of mutation that I want to briefly discuss is a nonsense mutation. So, a nonsense mutation can arise if as a result of insertion deletions or point mutations. So, both of these categories of mutations contain nonsense mutations. So, a nonsense mutation is a mutation when we basically change a codon that codes for an amino acid into a codon that is a stop codon, that terminates our polypeptide chain, and this basically terminates the polypeptide chain prematurely. And this causes or creates a non functional protein. So, basically, this concludes our discussion on genetic mutations.
