Objectives ____________________the usefulness of some transgenic organisms to humans. Describe

Genetic engineering has spurred the growth of biotechnology. Transgenic Organisms An organism described as_______________, contains genes from other species. Genetic engineering has spurred the growth of biotechnology. transgenic

Transgenic Microorganisms Transgenic bacteria produce important substances _______________for health and industry. Transgenic bacteria have been used to produce: insulin growth hormone clotting factor useful

Transgenic Animals Transgenic animals have been used to study genes and to __________________the food supply. Mice have been produced with human genes that make their immune systems act similarly to those of humans. This allows scientists to ______________the effects of diseases on the human immune system. improve study

Cloning A _______________is a member of a population of genetically identical cells produced from a single cell. In 1997, Ian Wilmut cloned a sheep called Dolly. clone

Researchers hope cloning will enable them to make copies of transgenic animals and help save endangered species. Studies suggest that cloned animals may suffer from a number of _____________________and health problems. genetic defects
