What is a mutation?

A mutation is a change that occurs in the genetic material of an organism, usually in its DNA sequence. These changes can be caused by errors that occur during the replication of DNA or by external factors, such as exposure to radiation or chemicals. Mutations can be beneficial, harmful or have no apparent effect on the organism. They can occur in all types of living organisms, from bacteria to humans, and can be inherited or acquired during a lifetime. Mutations play a role in evolution as they introduce genetic variations, which can lead to the development of new traits and ultimately the emergence of new species.
