Biotechnology

Biotechnology leverages our understanding of living organisms to develop improved products and processes. This includes genetic modifications aimed at enhancing traits in organisms, such as producing transgenic organisms that express desired genes. Key techniques in biotechnology include the use of restriction enzymes, recombinant DNA, gene therapy, and the Human Genome Project. Through these innovations, products like genetically modified crops and insulin are created, showcasing the practical benefits of biotechnology in agriculture, medicine, and beyond.

Presentation Transcript

  1. Biotechnology Making the products you buy. . . better?

  2. Biotechnology: Any process that uses our understanding of living things to create a product. http://www.ncris.dest.gov.au/NR/rdonlyres/512FD9F0-E40D-4A95-85D2-4DAA0B5B218F/0/BiotechnologyProgenfacility2.JPG

  3. 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

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

  5. 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

  6. 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

  7. Genetically modified products: Altering the DNA of an organism to get it to express different traits. http://images.google.com/imgres?imgurl=http://www.peaceproject.com/graphics/dvds/larger/DVD51.jpg&imgrefurl=http://www.peaceproject.com/books/dvd51.htm&h=425&w=301&sz=34&hl=en&start=4&tbnid=z2kXaaU36oWWsM:&tbnh=126&tbnw=89&prev=/images%3Fq%3Dgenetically%2Bmodified%26gbv%3D2%26hl%3Den%26safe%3Dactive%26sa%3DX

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

  9. 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
