  1. Cloning or Genetic Modification What’s the difference?

  2. In the novel Jurassic Parkby Michael Crichton: • Scientists used ancient dinosaur DNA trapped in amber to clone extinct species. • They designed a theme park around this idea to earn profits on tourism. • The cloned dinosaurs eventually became uncontrollable and the scientists abandoned their project, sacrificing many lives along with their investment. https://www.flickr.com/photos/ffg/3113602118/ Dave Walker/CC.BY.2.0

  3. What’s Your Opinion? • Do you think there was anything the scientists could have done to reduce the risk? • Is there any way to bring extinct organisms back by any other means? http://images.cdn.fotopedia.com/flickr-457428714-original.jpg Scott Kinmartin CC.BY.2.0

  4. Many organisms have been cloned in the past 50 years with varying success • Mice, cattle, sheep, cat, deer, dog, horse, mule, ox, rabbit and rat, and a rhesus monkey have all been cloned. • Some lived longer than others. • Dolly the sheep (cloned in 1996) only lived about 6 years. http://en.wikipedia.org/wiki/Dolly_%28sheep%29 Steven Walling/CC.

  5. Cloning vs. Genetic Modification • Cloning humans is currently not allowed by law in any country on Earth. • Genetic modification is currently used to replace or repair mutated genes or to add new traits to an organism.

  6. Genetic Modification • Defined as changing the genes of an organism using biotechnology. • Usually involves one gene, or a few genes, that contain instructions for a specific trait. • This has an effect on the resulting trait in the organism. • Can be used to replace or repair existing genes, or introduce brand new genes for new traits.

  7. Genetically Modified Organisms • Some modified traits are easily visible like • these glowing animals. • And some modified traits are not easy to see, such as the disease resistance introduced to these fruits and vegetables Glofish and Green Luminescent Mice http://commons.wikimedia.org/wiki/File:GloFish.jpg CC.BY.2.0 Sweet Corn Hawaiian Papaya http://commons.wikimedia.org/wiki/File:VegCorn.jpg CC.BY.2.0 http://en.wikipedia.org/wiki/Genetically_modified_food#mediaviewer/File:Papaya_sunset.jpg CC.BY.2.0

  8. Where we go from here: • Using the website Learn.Genetics, you will find out how cloning and genetic modification are actually done. • Complete all answers on your answer sheet. • Peer review a friend’s answers, correct if needed. Give back to your friend. • Organize your new ideas with a graphic organizer. • Move around to discussion stations, decide how far you would go in gene modification or cloning. • Assessment: You are the editor of a magazine! Readers have submitted questions about genetic modification and cloning, and you correct their misconceptions. Be as specific as you can to show what you know!
