mutation - (pronounced) (avoid myoo-TAY) Any change in the DNA sequence of a cell. Mutations can be caused by errors during cell division, or they can be caused by exposure to DNA-damaging agents in the environment. Mutations can be harmful, beneficial, or ineffective. If they are found in cells that produce eggs or sperm, they can be inherited; If mutations occur in other cell types, they are not inherited. Certain mutations can lead to cancer or other diseases. A mutation is sometimes called a variant
