Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Dolly the sheep was a sheep that was born to an unrelated mom. Her genome was inserted into an egg that had the DNA removed. This is an example of ____
A
Genetic engineering
B
Cloning
Explanation: 

Detailed explanation-1: -Dolly remained alive and well long after her birth, with a functional heart, liver, brain, and other organs, all derived genetically from the nuclear DNA of an adult mammary gland cell. The technique used to produce her later became known as somatic cell nuclear transfer (SCNT).

Detailed explanation-2: -Dolly was cloned from a cell taken from the mammary gland of a six-year-old Finn Dorset sheep and an egg cell taken from a Scottish Blackface sheep.

Detailed explanation-3: -Dolly is a transgenic creature. Q. A sheep Dolly was the first animal cloned from a cell taken from the udder of an adult transgenic sheep.

Detailed explanation-4: -Cloning is a method that scientists use to produce a genetic copy of another individual. In other words, Dolly was a clone of her mother. Well, actually, Dolly had three mothers. One mother gave Dolly her DNA, one mother supplied an egg, and the third mother, her surrogate mother, gave birth to her.
