Mutation causes changes to DNA base sequence, may cause variations that are adaptations, can be caused by radiation and X-rays but are not always harmful.
What are mutations?
They are changes to the DNA base sequence of organisms. They can be caused by a variety of processes both naturally and artificially. Radiations and X-rays are some of the things that can induce mutation.
Changes to the DNA base sequence of organisms may cause physical variations that will make organisms to be more adaptable to their environments.
Some mutations can also be deleterious to organisms. In other words, mutations can be beneficial as well as harmful.
