Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Genetic engineering has produced goats whose milk contains proteins that can be used as medicines. This effect was produced by
A
mixing genes into the milk
B
injecting genes into the goats udders
C
inserting foreign genes into fertilized goat eggs
D
genetically modifying the nutritional needs of the goats offspring
Explanation: 

Detailed explanation-1: -The researchers introduced the human gene into the goat genome to produce higher levels of lysozyme in goats’ milk. The hope is that milk produced by these transgenic goats could one day be used to help prevent deadly diarrhea in weaned children of the developing world.

Detailed explanation-2: -In pharming, these genetically modified (transgenic) animals are used mostly to make human proteins that have medicinal value. The protein encoded by the transgene is secreted into the animal’s milk, eggs, or blood, and then collected and purified.

Detailed explanation-3: -Pronuclear injection and somatic cell nuclear transfer represent the two primary procedures for the generation of genetically modified sheep and goats. Further assisted tools have emerged to enhance the efficiency of genetic modification and to simplify the generation of genetically modified founders.

Detailed explanation-4: -Transgenic goats are obtained by pronuclear microinjection and somatic cell nuclear transfer. After the maturation of the transgenic female goats, they produce milk containing the protein from which spider silk is made.
