There are three different types of cloning: recombinant DNA technology (DNA cloning), reproductive cloning, and therapeutic cloning (Cloning). DNA cloning is the transfer of a DNA fragment of one organism to a self-replicating genetic element such as a bacterial plasmid. The DNA fragment can be propagated in a foreign host cell. This technology has been around for about 30 years and is commonly used in molecular biology. Reproductive cloning is a technology used to generate an animal with the same nuclear DNA as another currently or previously existing animal. Dolly was created this way by transferring genetic material from the nucleus of a donor adult cell to an egg which has had its genetic material removed. The reconstructed egg is treated with chemicals or electric current to stimulate cell division, and once the cloned embryo reaches
