Definition of Cloning EssayCloning is the process of creating an like copy of an original. It is a single kiosk or multi-cellular organism that is genetically identical to another living organism. Cloning can also occur when two genetically identical individuals are produced by accident like identical twins, precisely in common scientific language the clone is an identical copy by some conscious design. Cloning an organism is to create a wise organism with the same genetic information as an existing one. This can involve the transfer of a cell thermonuclear in which the nucleus is withdraw from an egg cell and replaced with a nucleus extracted from a cell of the organism to be cloned. AS the nucleus contains all of the genetic information of life, the receiving egg cell will develop into an organism genetically identical to the original nucleus.Brief history IICloning started with frogs and toads back into the 1970s. Experiments have been long performed with plants and ani mal embryos. The bird is the first fully grown mammal to be cloned in 1996. The dolly was developing by using the process call somatic cell nuclear transfer which consists of DNA coming from a single cell aspiren from her mother egg, which is fused with the mammary cell. The fused cell then develops into an embryo, which is implanted in a surrogate sheep. The embryo grows into a lamb, which is genetically identical to the donor sheep (Dr.Lee Silver, Human Cloning, 1998).After the dolly, cows was being clone in 1998, pigs in 2000.The first kat was cloned in2001and in2004 a bull was cloned. With this successful process of the dolly scientists believe that human cloning may be possible. The first human cloned embryos were not until 2001. Currently in that respect are a lot of problems of getting Human clones. It is still not proven that scientists could successfully clone a human still it will take a lot of trial to even be successful in the case of animal cloning 277 sheep died be fore the dolly was born. There so galore(postnominal) questions about human fertility, scientists could not be sure that an identical human clone will ever be possible.
