Genetically Modified Organisms (Carrie)

  1. 1. Our Unit Goals: DNA, Heredity & Genetics Structure dictates Genes & Heredity Biotechnology & function (Classical Genetics) Modern Genetics Labs/Activities Lectures/ Lectures/ Labs/Activities Labs/Activities Family Lectures/ Discussions Discussions Plasmid lab Build DNA Tree/Pedigree Discussions Technology Double Helix Virtual model Chromonoodle History of DNA Aplplications Central Dogma Punnett Squares genetics lab & Ethics Students realize that science, including genetics, is part of their everyday lives. Hence, the ‘Everyday Scientist’ theme/narrative.Background picture from http://movies-wayneaddisoncyrus.blogspot.com/2011/03/dna-strand-of-bases.html
  2. 2. Our Lab Goals: *GM vs. nonGM NOT stated for students* Identify visible and less obvious similarities and Explain how DNA gives Visualize and label parts difference between rise to physical traits. of a plant cell. groups of organisms. Begin to think about how technology and Comprehend genetic science impact society engineering techniques. (important part of final unit project – slide#11).http://www.google.com/imgres?start=285&um=1&hl=en&biw=943&bih=426&tbm=isch&tbnid=MbiibBJvh0oH8M:&imgrefurl=http://www.healingtalks.com/tag/gmos/&docid=4HpvXfmBaJsfPM&imgurl=http://www.healingtalks.com/wp-content/uploads/2011/11/California-GMO-labelling-initiative-is-filed.jpg&w=640&h=360&ei=duljT4eeCaP30gGLyPGwCA&zoom=1

  9. 9. Possible Class Conclusions Genes are causing different physical traits Different band patterns = different DNA Larger uncut DNA samples = genes inserted Smaller uncut DNA samples = genes deleted
