Biology Quiz: Types Of Genetic Mutations!

There are different types of genetic mutations in the world today, and all these are due to the DNA of a person being change through the addition of a foreign gene. Most of the mutations we hear about cause illnesses, and as a medical practitioner, you should know how to correct or create mutations. Do take the quiz and see how well you will do.
