The term "mutation" describes a change that occurs in the DNA sequence of an organism. This change can be attributed to a great variety of reasons, such as mistakes when the DNA is copied, or due to environmental factors. This change contributes to the evolutionary process, and allows an organism to modify its structure and attributes.
