Shweta Patro/Anna Isachenko Slide 2: We’re going to talk about recombinant DNA technology, the technique used to create genetically modified organisms. We’re also going to talk about the Asilomar conference on recombinant DNA. Slide 3: The point of recomb. DNA tech is to change an organism’s DNA. Because if you change the DNA of an organism, you can also change the proteins that it produces. Slide 4: In this case study the organism is corn, and it has been genetically modified to express proteins that make the plant resistant to herbicides and pests. Slide 5: So how exactly is this done? It all started with Stanley Cohen and Herbert Boyer, who found a way to take a gene from a certain organism and put it into another one. Cohen and Boyer’s method was a combination of the work that both of them did independently. Slide 6: The first guy, Stanley Cohen was a researcher at Stanford. His lab was working with bacteria, which can

Unformatted text preview: assimilate DNA from their environments into their own DNA ring. Cohen’s lab did two things: First, they were able to get bacteria to assimilate a piece of antibiotic resistant DNA into the bacteria’s genome. Second, they were able to isolate and clone the gene that produced this antibiotic resistant protein. Slide 7: The second guy, Herbert Boyer was a researcher at UC San Francisco. Boyer's lab isolated an enzyme that could be used to cut strings of DNA into precise segments that could be attached to other pieces of DNA. Slide 8: Both of them combined their work into a discovery. Slide 9: Boyer's enzyme could introduce specific DNA segments to plasmids. Slide 10: These plasmids could then be used in Cohen’s process as a vehicle to clone particular genes....
