How have transgenic animals proved to be beneficial in:(i) Production of biological products?(ii) Chemical safety testing?

Answer»

(i) Rosie–the transgenic cow, produced human proteins containing human αlactalbumin. Transgenic animals have been made to produce 2- 1-antitrypsin used to treat emphysema.

(ii) Toxicity testing – Transgenic animals are more sensitive to toxic substances, so the results are obtained in less time.
