Question

Chemical mutagens are more dangerous than radiations. Justify from the following statements.

• A. Exposure to them is more frequent
• B. There is protection from radiations but not chemicals
• C. Chemically caused mutations are far more deleterious
• D. Both A and B

Answer 1

The correct option is D Both A and B

Chemical mutagens are defined as those compounds that increase the frequency of some types of mutations. They vary in their potency since this term reflects their ability to enter the cell, their reactivity with DNA, their general toxicity, and the likelihood that the type of chemical change they introduce into the DNA will be corrected by a repair system. The concerns is in the use of mutagens. Most of the following mutagens are used in vivo treatments, but some of them can also be used in vitro.
Chemical mutagens are more dangerous than radiations. It is because exposure to them is more frequent and there is protection from radiations but not chemicals.
