Question

Toxicity of drugs on humans can be studied by using transgenic animals by

• A. Introducing a gene that shows change in physiology of organism
• B. Introducing a complementary gene into organism
• C. Introducing a gene that makes them more sensitive to toxic substances
• D. All of the these

Answer 1

The correct option is C Introducing a gene that makes them more sensitive to toxic substances

Toxicity of drugs on human can be studied by using transgenic animals by introducing a gene that makes them more sensitive to toxic substances. These transgenic animals are then exposed to the toxin and the effects and levels of their toxicity can be studied. Since these transgenic animals have a predisposition to be susceptible to a certain toxin, researchers can easily determine safe dosages by using these transgenic animals.
