This process is referred to as the Nuclear Transfer or Nuclear Substitution. DNA molecules are the strings of protein that hold genetic coding.

... animals (Levine 1). In 1938, Hans Speman proposed cloning a mammal by transplanting an adult cell's nucleus into a fertilized egg. This process is called nuclear transfer and was initially used to clone a frog in 1952 (Sinha 59). Using this process, nuclear DNA from the body cell of a donor frog was injected into the egg cell of a recipient frog whose nuclear genetic material was removed. The fused cells divided ... just like a normal fertilized egg and formed an embryo that was genetically identical to the donor frog. In 1980 mice were successfully ...

In the cloning process, a scientist takes the genetic information of an organism and inserts it into an unfertilized egg cell from a member of the same species (MacKinnon, 4).
