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

The UV rays could harm the DNA of skin cells. Skin cancers begin when the said harm affects the genes’ DNA which control the growth of the skin cell. There are three main types of UV rays, the first one is called UVA rays. They can damage the DNA of skin cells and age them. They are connected to long-term skin damage, however they are also thought to cause some skin cancers. The second one is called UVB rays, they have a little more energy than UVA rays. They are thought to cause most skin cancers as well. They can immediately damage the DNA of skin cells. The third one is called UVC rays, they have a greater amount of energy than the other types of UV rays, however they don’t usually cause skin cancer.

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

Explanation:

Cancer occurs when gene mutations in a cell result in uncontrolled cell division. If cells are exposed to certain chemicals or certain types of radiation, the number of mutations will increase, as well as the chance of cancer.

Therefore, the mice that were exposed to high levels of UV radiation were more likely to acquire cancer because UV radiation can alter an organism's DNA molecules and cause mutations.
