Question

Rosie was a historically significant transgenic animal primarily because she demonstrated which capability?

Options

• The capacity to reproduce without biological constraints

• Enhanced resistance to all infectious diseases

• The production of human protein-enriched milk containing alpha-lactalbumin as the first transgenic cow

• The ability to survive in extreme environmental conditions

Answer 1

Rosie was the first transgenic cow, making her a highly important historical example in biotechnology. Her significance lies in her ability to produce human protein-enriched milk containing alpha-lactalbumin, demonstrating that transgenic animals could serve as biological factories for producing therapeutic human proteins. This breakthrough established the concept of using animals as bioreactors for pharmaceutical protein production, a major application of transgenic technology.
