Question

Mutations can be artificially induced by ______.

Options

• X-rays

• infra-red rays

• visible light

• radio waves

Answer 1

Mutations can be artificially induced by X-rays.

Explanation:

Mutations can be artificially induced by mutagenic agents such as short-wave electromagnetic radiations including X-rays, gamma rays, and ultraviolet rays. Among the options given, X-rays are ionizing radiations that can cause mutations by breaking the DNA strands, leading to changes in the genetic material. Infra-red rays, visible light, and radio waves do not have enough energy to induce mutations effectively. Hence, X-rays are commonly used to induce mutations artificially in mutation breeding and genetic studies.
