Learn.Genetics™ Animal Farm Episode 1, Part 3 of 10. 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. With genetic engineering, genes from completely different species can be inserted into one another.
For example, scientists in Taiwan have successfully inserted jellyfish genes into pigs in order to make them glow in the dark. 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 Some GE crops are actually classified as pesticides. GE Animals. Meet the Super Cow. Chpt 3 One Wrong Letter. Simulations. 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.
