Making Medicines. Not long ago, if you were diabetic, the insulin your doctor prescribed would have come from a pig. If you required human growth hormone, it would have come from human cadavers, a source that is costly, not to mention a little creepy. Now, these and other medicines can be made by specially-modified bacteria, called transgenic bacteria. These single-celled organisms have foreign genes along side their own DNA.
