Question

With respect to the chemical safety testing, transgenic animals are made to carry genes which makes them

• A. Both b and c are correct
• B. insensitive to toxic chemicals
• C. sensitive to toxic chemicals and then these animals are exposed to the nontoxic substances
• D. sensitive to toxic chemicals

Answer 1

The correct option is D sensitive to toxic chemicals

In chemical safety testing or toxicity testing by using transgenic animals, these animals are made to carry the genes which makes them more sensitive to toxic substances/chemicals than non-transgenic animals. They are then exposed to the toxic substances and the effects are studied. Toxicity testing in such animals will allow us to obtain reliable results in comparatively less time.
