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.n some cases, the mutation occurs in a personâs egg or sperm cell but is not present in any of the personâs other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite.
What two types of gene mutations? 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 â¦is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.
