If the proteins making up a gene were changed or mutated, what impact would this likely have on an organism?

Mutations can also lead to the development of cancer. For example, if genes coding for proteins involved in cellular growth are mutated, cells may grow and divide out of control. Some cancer-causing mutations can be inherited while others can be acquired through exposure to carcinogens like UV radiation, chemicals, or cigarette smoke.

Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.
