Question

Explain briefly how the transgenic animals benefit the human beings.

Accepted Answer

Animals whose DNA is manipulated to possess and express an extra (foreign) gene are known as transgenic animals. Following are the common ways in which they are beneficial:

Biological products: Useful biological products can be produced by introducing into transgenic animals the portion of DNA (or genes) which codes for a particular product. For example, human protein (a-1-antitrypsin) is used to treat emphysema.

Study of disease: Study of genes which are responsible for diseases in human and their treatment. Transgenic models have been developed for many human diseases like cancer, cystic fibrosis, rheumatoid arthritis and Alzheimer’s disease.

Study of normal physiology and development: Useful to study gene regulation, their effect on the normal functions of the body and its development. For example, study of complex growth factors like insulin-like growth factor.
