WebA mutation is a change in DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, and its physiology. So a change in an organism’s DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur. WebMost changes to a person’s DNA don't affect their genetic makeup and won’t lead to any health problems, but some mutations cause genetic conditions that could affect your health.
