Question

which is the most efficient way to avoid dna mutations from uv radiation?
avoid getting x - rays at the doctor’s office.
avoid protective shields during x - rays.
avoid uv radiation by wearing sunscreen.
avoid uv radiation by using a tanning bed.

Explanation:

To avoid DNA mutations from UV radiation, we analyze each option:

• Avoiding X - rays at the doctor’s office is irrelevant to UV radiation (X - rays are a different type of radiation).
• Avoiding protective shields during X - rays is also about X - rays, not UV, and is unsafe.
• Wearing sunscreen blocks UV radiation from the sun, which is a major source of UV that causes DNA mutations.
• Using a tanning bed exposes one to UV radiation, increasing the risk of mutations.

Answer:

C. Avoid UV radiation by wearing sunscreen.
