Answer:

UV radiation can alter an organism's DNA molecules and cause mutations.

Explanation:

The penetration of Ultraviolet radiation into the mice will react with the DNA bases thereby causing oxidation of DNA.

However, during replications, the reactions between ultraviolet radiation and DNA bases usually fails to pair normally, hence, a mutation occurs. This is otherwise known as Oxidative mutations.

Hence, in this case, the correct answer is "UV radiation can alter an organism's DNA molecules and cause mutations."
