  1. Biotechnology According to some…Making the products you buy. . .better!

  2. Any process that uses our understanding of living things to create a product. Altering the DNA of an organism to get it to express different traits. Biotechnology & Genetically Modified Products

  3. Gene Therapy: • Application of genetic engineering techniques to alter or replace defective genes. http://www.acceleratingfuture.com/michael/blog/images/Gene_therapy.jpg

  4. Gene/Sequence of Interest - A piece of DNA that codes for a protein we want more of……for example, the gene for human insulin. • Plasmid – circular piece of DNA found in bacteria • Recombinant DNA – DNA produced by combining DNA samples from different organisms. http://img.blogcu.com/uploads/kedicikkopekcik_insrton.jpg

  5. Restriction Enzymes: Enzymes that cut DNA at certain sequences. http://www.accessexcellence.org/RC/VL/GG/images/restriction.gif

  6. Transformation: • The changing of one strain of bacteria into another strain. • This process can be completed using other organisms as well. http://www.anselm.edu/homepage/jpitocch/genbio/plantplasmidtechn.JPG

  7. Transgenic Organisms: Any organism whose genome incorporates and expresses genes from another organism of the same or a different species. http://images.google.com/imgres?imgurl=http://www.umaine.edu/bmmb/images/faculty/mayerrsrch3.jpg&imgrefurl=http://www.umaine.edu/bmmb/faculty/index.php/profile/greg_mayer&h=508&w=640&sz=126&hl=en&start=32&tbnid=3FrSMECBDttBMM:&tbnh=109&tbnw=137&prev=/images%3Fq%3Dtransgenic%2Borganism%26start%3D18%26gbv%3D2%26ndsp%3D18%26hl%3Den%26safe%3Dactive%26sa%3DN

  8. Human Genome Project • In 1990, scientists from several different countries began a project to analyze and sequence all the genes found in human DNA. • In 2000, this project was essentially completed. • Potential uses: • Medical research – using gene therapy to cure genetic disorders. • Trace human lineage. http://www.scienceclarified.com/images/uesc_06_img0300.jpg
