BioBytes: Genetically Engineered Animals

Disease resistant animals, environmentally friendly livestock, pharmaceuticals produced by goats - are these really possible? With the help of biotechnology, scientists are discovering new ways to genetically engineer animals to not only help them become resistant to deadly diseases and reduce their carbon footprint, but also to produce proteins used in pharmaceuticals to treat blood clots, malaria, hemophilia, and arthritis. Dr. Targan explains how genetic engineering in animals works, as well as a few of the benefits that both animals and humans can appreciate.
