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.hese changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if a mistake is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed on to the next generation.
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 is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.he 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 is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message.
