Now, how exactly do genetic mutations actually arise? Well, our genetic mutations can arise as a result out of two things. They can either arise spontaneously due to the mistakes that take place in the natural processes inside the cell, or they can also arise. They can be induced by outside physical or chemical agents by outside forces, such as UV radiation. So if our mutation arises as a result of the natural processes that take place inside our bodies, such as a mistake that takes place during DNA replication, in which our DNA polymerase does not actually fix the mistake, such a mistake, such a mutation, is known as a spontaneous mutation. On the other hand, those mutations that arise in the DNA as a result of some outside factor, some outside physical or chemical agents, such as a mutagen, these types of mutations that are induced inside our DNA are known as induced mutations.
