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.
A point mutation is a change in a single base pair in DNA. A change in a single nitrogenous base can change the entire structure of a protein because a change in a single aminâ¦o acid can affect the shape of the protein. A frameshift mutation is a mutation in which a single base is added or deleted from DNA. A single base is lost from a DNA strand which causes this new sequence with the deleted base, to be transcribed into mRNA. Then, the mRNA is out of position by one base. As a result, every codonafter the deleted base is different.
