Does a dna mutation always change the protein
WebPoint Mutations. Sometimes a mutation alters a single nucleotide in the DNA molecule. When only one nucleotide has been altered, the mutation is classified as a point mutation.When a purine nitrogenous base is changed to another purine (e.g., adenine for guanine) or a pyrimidine nitrogenous base is exchanged for another pyrimidine (e.g., … WebA mutation is a change in DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, and its physiology. So a change in an organism’s DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not ...
