Biotechnology

Through biotechnology, segments of DNA can be introduced in the genetic inheritance of a bacterium. Human DNA supplies bacterial cells with instructions to synthesise proteins that the bacteria usually do not synthesise. This has led to the production of proteins that are very important to treat some diseases. Nowadays, substances that in the past used to be extracted from natural sources and often available in limited amounts can be obtained from bacteria in large amounts and at low costs. The protein molecules of bacterial origin that are useful in medicine include insulin for diabetes, interferon for viral infections and the growth hormone.
