Which of the following agents are unlikely to cause mutations in DNA?

Question

Quizplus · Accepted Answer

Radiation from an incandescent lightbulb is unlikely to cause mutations in DNA as the light produced by these bulbs is in the form of visible light, which does not have enough energy to break bonds in DNA. However, it is still recommended to use energy-efficient bulbs as they emit less heat and reduce the risk of fire hazards. The other options listed are known to cause mutations in DNA in different ways. Aflatoxins, which are produced by moldy grains, can intercalate with DNA and cause mispairings, while free radicals can damage DNA by oxidizing its bases. Ultraviolet radiation from sunlight can also cause direct damage to DNA by inducing thymine dimers.
