Genetically engineered bacteria can be used to produce a variety of products including medically important proteins, vaccines, commercially important proteins, and DNA for study. They are also used as research tools. Genetic engineering of plants can be used to develop pest-resistant plants, herbicide-resistant plants and plants with improved nutritional value. Through genetic engineering, edible vaccines might one day be possible.
■ Name two diseases that are treated using proteins produced by genetically engineered microorganisms.
■ Describe the attributes of two different types of transgenic plants.
■ Potatoes are relatively easy to genetically engineer, which is why they are being used in the edible vaccine studies. Why will edible vaccines eventually require the engineering of a food product that is routinely consumed raw?
