Dr. Drew is studying the effect of overexposure to UV radiation in mice. He discovers that mice that are exposed to high levels of UV radiation are much more likely to acquire cancer than mice that are not exposed to UV radiation. Which of the following best explains why high levels of UV radiation can cause cancer in mice?

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."
