Explain five benefits of creating transgenic animals.

Explanation

To study basic biological process: Transgenic animals are used to study gene regulation and its effect on normal functions of the body and its development
E.g., Study of complex factors involved in growth such as insulin -like growth factor.
Normal physiology and development: To study basic biological process transgenic animals.
Study of diseases: Transgenic animal models are used to understand the contribution of genes in the development of disease and to investigate new treatments for diseases like fibrosis, rheumatoid arthritis, Alzheimer.s etc
Biological products: Transgenic were created to produce milk containing particular human proteins, (`alpha` - 1- antitrypsin) which may help, in the treatment of human emphysema.
E.g., Rosie is the first transgenic cow (1997) that produced the milk enriched with human protein, `alpha` -lactalbumin (2.4g per Itr) which is nutritionally more balanced product for human babies than natural cow milk.
Vaccine safety : Transgenic mice are being developed for us in testing for the safety of vaccines ( polio vaccine) before they are used on human
Chemical safety testing : Transgenic animals are exposed to toxic substances to study their effects in less time
