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.
One gene to create us all: Single mutation in DNA may have been responsible for evolution of multicellular life. A single genetic mutation may have been responsible for allowing multicellular life â and eventually humans â to evolve on Earth. Biologists have found a lone gene capable of turning single celled organisms into multicellular organisms. Researchers behind the discovery believe it may have been a tweak like this in the DNA of ancient organisms on Earth which led to the evolution of complex life. They found that by deleting a single gene called ACE2, they could control whether a brewer's yeast grew as single cells or in multicellcular forms.
