I believe a simple change in DNA results in Mutation. A mutation is a random spontaneous changes that occur in the genetic make up of an organism ( in the DNA sequences). The mutation are either due to mistakes when DNA are being copied or as a result of environmental factors such as UV light and cigarette smokes among other mutagens. Mutations may be either gene mutation (permanent alteration in the DNA sequence that makes up a  gene) or chromosomal mutation.

The answer is mutation because a small change in a gene can change how that gene works. This is because we've changed the instructions for making that protein. DNA changes in a gene are called mutations. Mutations happen in many ways. For example: DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

Hope this Helps :)
