Caption: The first step during SCNT is enucleation or removal of nuclear genetic material (chromosomal) from a human egg. An egg is positioned with holding pipette (on the left) and egg's chromosomes are visualized under polarized microscope. A hole is made in the egg's shell (zone pellucida) using a laser and a smaller pipette (on the right) is inserted through the opening. The chromosomes then sucked in inside the pipette and slowly removed from the egg.
