Stem cells produced from cloning technique

The video tutorial explains a process involving a genetic disease where a donor egg is stripped of its DNA and a skin cell is inserted into the egg. Electricity is used to stimulate the egg to divide and form an embryo. Stem cells are then extracted from the embryo, which can be used to grow muscle, liver, and nerve cells. These cells can be transplanted into the original patient without the risk of rejection.
