Transcription de la présentation

  1. Applied Genetics Ch. 24 How the Principles of Genetics are used.

  2. How have humans applied Genetics? • People have bread plants and animals for specific desirable traits for thousands of years. • Selective breedingis the crossing of plants and animals with desired characteristics to produce offspring with those characteristics.

  3. Other cases of Selective Breeding • Disease resistant plants such as corn and wheat. • Variations of flowers for color or shape • Bigger, leaner livestock

  4. How is a Hybrid produced? • Sometimes breed offspring with two or more desired traits • Hybridizationis the crossing of two different but related species. • Ex. Mule (horse/donkey) • Beefalo

  5. Beefalo Mule

  6. Some plants offspring are bread together? • Some desired traits are amplified by inbreeding offspring of the same species. • This could make a desired trait more prominent, but will not allow new genes to enter the species.

  7. Where is the future of Genetics? • Genetic Engineering is the process in which genes or pieces of DNA are transferred from one organism to another. • Combining DNA from one organism with the DNA of another. • This process is called recombinant DNA

  8. Recombinant DNA

  9. How does it happen? • Usually a gene from a higher organism is placed into to a lower organism. • Human genes have been inserted into bacteria and yeast to produce certain proteins. Ex. Insulin • A gene is usually inserted into a ring of DNA from bacterial called a plasmid. • When the plasmid is placed in a bacteria the bacteria will produce the protein coded in the plasmid.

  10. Genetically Engineered Products • Medicine • Insulin, • Growth Hormone, • Vaccines, • interferons

  11. More Genetically Engineered Products • Agriculture • Crops that fight disease • Freeze resistant crops

  12. Cloning is apart of Genetic Engineering • Monkeys, sheep, and bacteria have already been cloned. • Should humans or parts of humans?

  13. Arguments For New medical breakthroughs Save lives Limit suffering from disease Arguments Against It is “playing God”! We are messing with nature. It may lead to a supreme race. Is Genetic Engineering Right?

  14. Web Task • Run a web search for information on genetic engineering. • Then in Microsoft Word, summarize two of the sites you found. Remember to give the addresses. • Once done with the summaries, give your opinion on genetic engineering and support it. • Save your paper to a disk and hand it in. Make sure your name is in the file name.

  15. Task Scoring Rubric • 5points for each site summarized in a complete well written paragraph. • 5points explaining your opinion of genetic engineering. • 5points for supporting your opinion with facts from sites or from the presentation. • Total of 20 points as a quiz grade.
