In most cloning cases, isolated genes or cells are cloned just for and only for scientific study and no new biological material or animals are crated. However, in 1997 an experiment was conducted and the result was the cloning of a sheep named Dolly. This process was different as it used a new technique of cloning known as somatic cell nuclear transfer. When the somatic cell nuclear transfer technique was first conducted the result was an animal that was a genetic twin, delayed in time however, of a sheep. This technique can also be used in the production of an embryo in which cells known as embryonic stem cells could be extracted. Once these cells were extracted they could potentially be used to research into the possible therapies for a vast number of diseases. As a result, the past five years a lot of the scientific and ethnical debates about somatic cell nuclear transfer has centered its attention in two areas for reproduction purposes or the production of a child and for the production of embryonic stem cells that are used for researching the causes of disease and maybe even come to a cure to the disease (Hanna, …show more content…
In nuclear transplantation cloning there is a single genetic parent the clone as the same exact genetic material as the animal the nucleus was removed from. The nuclear transplantation cloning technique differs from past cloning techniques in the area that it does not involve an existing embryo. Dolly’s cloning experiment was different because she is not genetically unique, when she was brought to the world she was genetically the same as an existing six year old ewe (Hanna,
