Question

Which is the most efficient way to avoid DNA mutations from UV radiation?

Answer 1

Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations. 

Answer 2

Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations. X-rays are not good for you, but they are usually necessary. Avoiding protective shields would increase the damage done by x-rays. Using a tanning bed would also increase UV radiation damage.
