Cloning

Science at the Edge: Cloning looks at how scientists are conducting research into the techniques of cloning. It shows how cloning occurs naturally in plants and micro-organisms, and how scientists and commercial companies are developing methods for cloning complex animals. There’s explanation of how Dolly the sheep was created, cell specialisation, nuclear transfer, xenotransplantation and stem cell research, and coverage of issues such as animal welfare, human cloning and designer babies.
