Question

Mutations can be artificially induced by

• A. X-rays
• B. Infra-red rays
• C. Visible light
• D. Radio waves

Answer 1

The correct option is A X-rays

• Physical mutagens. Ionizing radiations such as X-rays, gamma rays and alpha particles cause DNA breakage and other damages.
• Infra-red, visible and radio waves have longer wavelength and hence carry leser energy and cannot cause mutation.

So, the correct answer is 'X-rays'.
