What does adult cell cloning involve?
It involves taking an unfertilised egg cell and removing its genetic material (the nucleus) and then inserting a complete set of chromosomes from an adult body cell (e.g. skin cell) into the 'empty' egg cell. The egg cell is then stimulated by electric shock - this makes it divide, just like a normal embryo. When the embryo is a ball of cells, it's implanted into an adult female to grow into a genetically identical copy of the original adult body cell (clone)
