Animals in which a foreign of DNA is incorporated so as to obtain desired products or to study its effects on the biological processes are called the transgenic animals.
- E.g. – in 1997, Rosie a cow has been made transgenic to produce α-lactalbumin rich milk (2.4g/L).
Animal models have been developed to provide α-1-antitrypsin used by humans for the treatment of emphysema.
- In Canada, gene for spider web has been isolated from spiders & was inserted into goat. The goat now produces spider webs along with milk.
Due to the great tensile strength & light weight these spider web fibres are used for the development of military uniforms & tennis rackets.
