Genetic engineering has been successfully used for producing

  • transgenic mice for testing safety to polio vaccine before use in humans

  • transgenic models for studying new treatments for certain cardiac diseases

  • transgenic cow -Rosie which produces high-fat milk for making ghee

  • animals like bulls for farm work as they have a super power


A.

transgenic mice for testing safety to polio vaccine before use in humans

Transgenic mice are being developed for use in testing the safety of vaccines before they are used on humans. Transgenic mice are being used for testing toxicity of drugs. Transgenic animals are made that carry genes, which make them more sensitive animals. They are then exposed to the toxic substances and the effects studied. Toxicity testing in such animals will allow us to obtain results in less time.
