What are mutagens?

Affects only somatic cells Affects only plant cells Affects viral DNA Effects genetic cells both egg and sperm

Correct Answer:

Effects genetic cells both egg and sperm

Explanation:

Mutagens are agents that cause changes in DNA, producing mutations. They can affect many cell types, but mutations in germ cells—the eggs and the sperm—are the ones that can be passed to offspring. That’s why describing mutagens as affecting genetic cells in eggs and sperm best captures their potential to create heritable changes. The other statements are incomplete: mutagens are not limited to somatic cells, nor to plant cells, and while they can influence viral DNA in some contexts, their defining idea is DNA mutations in any organism, especially germ cells that can be inherited.
