Somatic Cell Nuclear Transfer Video

Somatic cell nuclear transfer (SCNT) is performed looking through a microscope and using small glass pipettes to handle human eggs and to remove and transfer nuclei from one cell to another. SCNT is used to produce clones of cells with the same genetic background as the donor nucleus.
