Distinguish among silent, missense, and nonsense point mutations.

Distinguish between silent, missense, and nonsense point mutations.A pointmutation is the change in a single nucleotide of DNA.There are three types of pointmutations-Silent mutations are mutated codon codes for the same amino acid.In thiscase there is no amino acid change and no effect on the organism.Missense mutations are mutated codon codes for a different amino acid.Inthis type of mutation there is one amino acid change and can have a variety ofeffects on the organism.A nonsense mutation is when a premature stop codon is created and theresult is that the polypeptide chain is shortened.This could have seriouseffects on the organism.
