Cloning has been going on in the natural world for about a thousand years. Cloning is simply the process of making a genetically identical copy. The biology online dictionary defines cloning as “the use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA.” The “Webster dictionary” defines it as “the technique of producing a genetically identical of an organism by replacing the nucleus of an unfertilized ovum with the nucleus of a body cell from the organism.” All these definitions generally explain exactly what cloning is. In that sense identical twins are clones because they have identical DNA. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots, which later sprouted new trees. There are three main types of cloning that are: recombinant DNA technology, reproductive cloning, and therapeutic cloning. Recombinant DNA technology is when a DNA fragment is transferred from one organism to a self replicating genetic element such as a bacterial plasmid. Scientist studying a particular gene often use plasmids to generate multiple copies of the same gene. Reproductive cloning is used to generate an animal that has the same nuclear DNA as another currently or previously existing animal. And therapeutic cloning is known as embryo cloning. Many cloned animals exist today, but a number of different species is limited. The first cloned animals were created by Hans Dreisch in the late 1800’s. Dreich’s original goal was to prove that genetic material is not lost during cell division. So he took a 2 celled embryo of a sea urchin and shook it in a beaker full of sea water until the two cells separated. Each grew independently, and formed a separate, whole sea urchin. The first mammal cloned from an adult DNA, was Dolly the sheep. Attempts of cloning certain species such as monkeys, chickens, horses, and dogs have been unsuccessful. Some species may be more resistant to somatic cells

nuclear transfer than others. Other successful cloning events include the kitten name CC, for copy cat, which was the first cloned pet, by Texas A&M University Scientist. The progression towards human cloning has been slow but steady. Now is the time for
