What is mutation? When and where do mutations occur?

A mutation is a change in the genome. Mutations happen by chance. Most mutations are negative in nature, but they can also have positive qualities. Thanks to beneficial mutations, the evolution of living organisms occurs. Mutations can be passed on to offspring, but this does not happen all the time. Mutations in the human body are happening all the time. Some are pronounced. You also need to remember that mutations are persistent, that is, they do not disappear and do not pass. Various chemicals or radiation can also cause changes.
