Rosie, the first transgenic cow, was produced to secrete milk that contained a human gene product, alpha-lactalbumin, which is nutritionally more balanced for human infants than natural bovine milk. This is a classic …

Transgenic animals contain an artificially inserted foreign gene in their genome, introduced to study gene function, produce useful biological products, or model human diseases.

A transgenic animal is one that has had its DNA manipulated to possess and express an extra (foreign) gene. Such animals are useful for studying:

• how genes are regulated and how they affect normal body functions and development.
• how genes contribute to disease, by allowing scientists to study animal models of human diseases. …
