Detailed explanation-1: -To make a clone, scientists transfer the DNA from an animal’s somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female’s uterus to grow.
Detailed explanation-2: -Gene cloning, which creates copies of genes or segments of DNA. Reproductive cloning, which creates copies of whole animals.
Detailed explanation-3: -There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer.
Detailed explanation-4: -1 No one has ever cloned a human being, though scientists have cloned animals other than Dolly, including dogs, pigs, cows, horses and cats. Part of the reason is that cloning can introduce profound genetic errors, which can result in early and painful death.
