Genetically Modified Food • ”Genetic Modification” (GM) – Use special technology to alter the genetic makeup of animals, plants, or bacteria • "genetically modified," "genetically engineered," or "transgenic” – Recombinant DNA technology • Combining genes from different organisms or altering organisms own DNA – Examples: • Bt corn produces own pesticide - gene from Bt bacteria • Roundup Ready Soybeans resist Roundup herbicide - altered soybean’s genes • GM salmon - grows faster and survives cold water - genes from other fish species Biotechnology (not always GM) • More general term • Use living organisms or their components, such as enzymes, to make products that include wine, cheese, beer, and yogurt • Examples: – Genetically modified bacteria produce an enzyme that separates milk to help make cheese • used to use rennet from a young calf’s stomach lining to get this enzyme – Malolactic bacteria is added to wine during fermentation; smoother and less acidic taste • No genetic modification here
