Cloning

A look at natural cloning and the main artificial cloning techniques devised by man, including embryo transplant and fusion cell cloning. Biology - Cells And DNA - Learning Points. Cloning occurs naturally in asexual reproduction in plants and animals, and in human reproduction when genetically identical twins are produced. Artificial cloning techniques include: embryonic cloning and fusion cell cloning. Embryonic cloning involves separating the cells of an embryo to create several identical embryos. Fusion cell cloning involves removing the nucleus of an egg and replacing this with a cell nucleus of a donor. A Twig Curriculum Film. Delivering key learning points.
