biology - nuclear transfer (clone creating)BackNuclear Transfer is a form of cloning. The steps involve removing the DNA from an oocyte and while(unfertilized egg), and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state. If the cloned cells are placed in the uterus of a female mammal, a cloned organism develops to term in rare instances. This is how Dolly the Sheep and many other species were cloned. Alternatively, if cells are extracted from the cloned cells during very early embryonic stages (blastocyst or morula), embryonic stem cells can be created. These cells can be grown in laboratories indefinitely and can theoretically be made into any of the 200+ cell types in the mammalian body, and thus are an extraordinary tool for biologists as well as a therapeutic agent with the potential to treat currently untreatable medical conditions.
