Human cloning is a very sensitive subject with its advantages and disadvantages. "Strictly speaking embryo cloning is a technique used by researchers and animal breeders to split a single embryo into two or more embryos that will have the exact same genetic information (Wall 1117)." "The procedures used in cloning human embryos are very similar to the cloning of animal embryos, except for the zona pellucida. The zona pellucida is a protective protein and polysaccharide membrane that covers the internal contents of the embryo, and provides the necessary nutrients for the first several cell divisions that occur within the embryo. Several sperm cells and mature egg cells are gathered from donors at fertility clinics, and are combined in a petri
dish using in vitro fertilization procedures to form an embryo. In an alternate process, already produced embryos are gathered from fertility clinics. The acquired embryo is placed in a petri dish and is allowed to develop into a mass of two to eight cells. Next a chemical solution is added to the zona pellucida that covers the embryo. After the zona pellucida is dissolved, the cells within the embryo are freed. These two to eight cells are collected by researchers and put in separate petri dishes (Hale 83)." "The cells are then coated with an artificial zona pellucida. The individual cells are then considered new embryos, all of which share the same exact genetic information. In effect at this point the science has produced multiple copies
