Cloning means producing a genetically identical copy of an individual. This is the way to be cloned. The scientists obtained his DNA from a skin cell and place them in the egg of a woman whose DNAwas extracted. A spark of electricity divide the egg and, after a few days, we get an embryo alike.

Much has been said in the press on human cloning. In reality, most scientists are not interested inproducing human clones. What scientists want to do is produce cloned human cells can be used to cure some diseases. That's how it might work: Imagine that you have a disease that is destroying partsof your brain slowly. Current treatments only reduce symptoms while the disease continues to cause injuries to his brain. Cloning offers hope of cure.

Scientists produce a cloned embryo using theDNA of epidermal cells. Then, withdraw the stem cells of the embryo, transforming them into brain cells and finally transplantarían your brain.

Cloning is in a different way of using stem cells tocure certain diseases. Some people prefer this way of obtaining stem cells. In the end, a cloned embryo is a genetic copy of someone who is already alive and who gave his consent. Obviously we all havethe right to decide what to do with our own DNA right?

In contrast, an embryo in the freezer of a fertility clinic was created from the unique mix of sperm and eggs, this is a union that willhappen only once, producing a completely unique set of genes that have the potential to become a unique individual.
Human cloning work One common method scientists may use to clone humans is, somaticcell nuclear transfer (SCNT), this method was used to clone the famous Dolly the sheep. SCNT begins when doctors take the egg from a donor and remove the nucleus of the egg, creating an enucleated egg. Acell, which contains DNA, is then taken from the person who is being cloned. The enucleated egg is then fused together with the cloning subject’s cell using electricity. This creates an embryo,...
