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.
The word mutation means a change in the genetic composition of a cell. Mutations can be divided into two main groups. The first group is gene mutations. These are chemical changes in the DNA [DNA: The material inside the nucleus of cells, carrying genetic information.DNA stands for Deoxyribonucleic Acid.] of the cell.he word mutation means a change in the genetic composition of a cell.
