Cloning

(library.thinkquest.org)
Cloning is a form of asexual reproduction which involves creating genetically identical genes or cells, plants or animals. The procedure of cloning is done by taking a gene from the animal or human and then putting that gene in another animals or human organisms. Scientists found out that cloning can also make identical twins by using a method called embryo splitting.
In July 1996, a team of Scottish scientists had the first cloning success. Dolly was the first ever cloned sheep. Therapeutic cloning is practiced to clone things such as organs and tissues for patients in need of them. Reproductive cloning is practiced for the purpose of actually producing a human that is genetically identical to somebody else. Human cloning is the creation of a genetically identical copy of an existing, or previously existing human, by growing cloned tissues from that individual. The term is generally used to refer to artificial human cloning; human clones in the form of identical twins are commonplace. Human cloning is amongst the most controversial forms of practice. One of the most ethically questionable problems with human cloning is farming of organs from clones. (Pence, 1998)

Human Cloning Essay
The possibility of human cloning was raised when Scottish scientists at Roslin Institute created the much-celebrated sheep "Dolly" (Lauritzen 57-64). Dolly aroused worldwide interest and concern because of the scientific and ethical implications in creating her. The feat, cited by Science magazine as the breakthrough of 1997, also generated uncertainty over the meaning of "cloning" -an umbrella term traditionally used by scientists to describe different processes for duplicating biological material. (Murray, 41) When the media report on cloning in the news, they are usually talking about only…

Ethics of Cloning and Genetic Manipulation
To daily life it gives the possibilities to cures for countless material improvements and diseases. The human genome project symbolized the hopes for the benefits of genetic manipulation, in the human species a vast international effort to categorize all the genes. For its potential for misuse genetic manipulation frightens many people. Either through simple bungling that might develop a biological holocaust which is caused by the viruses made by man or either through the Nazi style scheme for the control of the population. The single concept on the cutting edge of the genetic manipulation is…

Animal Cloning: Why it is moral
Cloning large animals, such as livestock, could be a viable source of organs for transplantation. Cloning also eliminates the possibility of incompatible organs as cells from the patient can used to clone the organ in another animal (Chou V). Pigs have been cloned and used for quite some time as a source of organ transplants into humans. Farm animals are being cloned worldwide to produce high-profit meat, milk or wool producing animals (Trust H). The process referred to as “animal pharming” produces large quantities of proteins, enzymes and therapeutic hormones cheaply from animals (Trust…

Cloning
This is not correct. Scientists do not copy embryos. They just take genetic material from a cell and put it into an empty egg cell. With this type of technology, they can develop nerve tissues, heart muscles as well as brain cells. Scientists believe that by cloning, any damage caused by illnesses can be repaired.…
