provide at least 3 real-world examples of current or future applications of biotechnology in medicine or agriculture
1. The most widespread application of genetic engineering in agriculture by far is in engineered crops. Thousands of such products have been field tested and over a dozen have been approved for commercial use. [ The traits most commonly introduced into crops are herbicide tolerance, insect tolerance, and virus tolerance.
2. Herbicide Tolerance
Case Study: Soybeans
allows crops to withstand otherwise lethal doses of herbicides, which are chemicals that kill plants. Some herbicides kill virtually all plants and cannot be used on crops. By offering crops tolerant to herbicides, chemical companies can expand the market for their products. Indeed, the major developers of herbicide-tolerant plants are companies that sell herbicides. The current set of commercially available herbicide-tolerant crops is tolerant to three herbicides based on three active ingredients: bromoxynil, glyphosate, and glufosinate.
3. Animals Engineered for Leaner Meat
Status: No livestock engineered for leaner meat is currently near commercialization. Research done early in the 1980s to genetically engineer leaner pigs failed because of unacceptable side effects, including low fertility, arthritis, and impaired immune systems. Some low level of research activity may still be underway. Pigs have been engineered with roundworm genes to produce their own omega-3 fatty acids, but have not been commercialized. ]
