A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. A neutral mutation has no harmful or beneficial effect on the organism. 2  Such mutations occur at a steady rate, forming the basis for the molecular clock. 3  In the neutral theory of molecular evolution, neutral mutations provide genetic drift as the basis for most variation at the molecular level.
