Chpt 3 One Wrong Letter Sustainable Table | Genetic Engineering Genetic engineering (GE) is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. When gene transfer occurs, the resulting organism is called transgenic or a GMO (genetically modified organism). Genetic engineering is different from traditional cross breeding, where genes can only be exchanged between closely related species. What are genes? All life is made up of one or more cells. During genetic engineering processes, specific genes are removed from one organism and inserted into another plant or animal, thus transferring specific traits. GE Crops Nearly 400 million acres of farmland worldwide are now used to grow GE crops such as cotton, corn, soybeans and rice. GE proponents claim genetically engineered crops use fewer pesticides than non-GE crops, when in reality GE plants can require even more chemicals. GE Animals Superweeds
Animal Farm Episode 1, Part 3 of 10 Peppered Moth Simulation Name:______________________________________________ Objective: Simulate changes in moth population due to pollution and predation, and observe how species can change over time. Introduction: Charles Darwin accumulated a tremendous collection of facts to support the theory of evolution by natural selection. One of his difficulties in demonstrating the theory, however, was the lack of an example of evolution over a short period of time, which could be observed as it was taking place in nature. Although Darwin was unaware of it, remarkable examples of evolution, which might have helped to persuade people of his theory, were in the countryside of his native England. The economic changes known as the industrial revolution began in the middle of the eighteenth century. Instructions: Click the link below to read more information on Kettlewell's study of moths.
