Genetic engineering refers to scientific techniques that alter the DNA of an organism. Scientists might remove entire segments of DNA, insert additional genes from other organisms, or change one base pair. Genetic engineering can enhance, modify, or take away specific abilities of an organism to do different things. For example, scientists have engineered E. coli bacteria to mass-produce insulin, providing a vital treatment for people with diabetes.
