Question

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

Explanation:

• Option 1: X - rays are not UV radiation. Avoiding X - rays at the doctor's office does not address UV - related DNA mutations.
• Option 2: Avoiding protective shields during X - rays is not relevant to avoiding UV - induced DNA mutations.
• Option 3: Wearing sunscreen helps block UV radiation, which is a major cause of DNA mutations. This is a direct way to prevent UV - related DNA damage.
• Option 4: Using a tanning bed exposes one to UV radiation, which can cause DNA mutations.

Answer:

C. Avoid UV radiation by wearing sunscreen.
