All in the genes.

Ian Wilmut (Roslin Institute), Dr. Patrick Dixon (author, "The Genetic Revolution"), Dr. Philip Kitchen (University of California), Dr. Alison Jones (Great Ormond Street Children's Hospital), Lord Robert Winston (Hammersmith Hospital), Prof. Mike Dexter (Christie Hospital, Manchester) and Dr. John Sulston (Sanger Centre, Cambridge) are among those discussing the implications for medical science of the Roslin Institute's achievement in cloning a sheep from adult cells. They discuss genetic diseases for which gene therapy, not yet a reality, could provide a cure. They also examind some social and ethical issues which may arise from genetic profiling. The second part of the programme looks at gene patenting and at the outlook for the use of animal organs for human transplants. It also contains a brief history of the Roslin Institute, and returns to sheep cloning to discuss the media's response. The laboratory procedures for cloning are shown. Part 3 turns to Alzheimer's disease and presents some views about screening for this condition. Given that potential victims can only be warned, not treated, is there any point in this? The programme concludes with a discussion of human cloning. Does the fact that it could be done mean that it will be done?
