Cloning The topic of cloning has much confusion and controversy behind it. Some people have heard of the sheep named Dolly, she was the first organism to be successfully cloned. Also pigs have been cloned, to be used for transplants. Cloning has many goals and purposes to achieve. People are hoping to bring back loved ones for reunions, help endangered species, or just have a friend. Although this may sound nice and also a great idea, but there will be consequences learned and cloning just might be a bad idea. The first thing to get cleared up is what is cloning and what is a clone. Cloning is the technique of producing a genetically identical duplicate of an organism. A clone is said to be all descendents derived asexually from a single individual, as by cuttings, bulbs, fission, mitosis, or by parthenogenesis reproduction. The scientific technology of cloning is the artificial production of organisms with the same genetic information. The technology behind cloning is called nuclear transfer. Nuclear transfer transfers a nucleus from one cell to an enucleated cell. The outcome of this transfer will make an organism with the exact genetic information as the donor cell.
