Q. 'Rosie', a transgenic cow, is known to produce a type of milk which has all the following characteristics, except it

NTA AbhyasNTA Abhyas 2022

Solution:

By combining nutritional and genetic interventions, researchers are developing 'medicine milk' rich in specific milk components that have implications in health as well as treatment. The extra gene (transgene) is present in every cell in the transgenic cow. However, it is only expressed in mammary tissue and therefore only in cow milk. One such example is Rosie — the first transgenic cow developed in 1997.
