 Hello, I'm going to show you our molecular biology laboratory where we manipulate gene activity in zebrafish embryos in order to investigate Alzheimer's disease. Through this door, you'll see our molecular biology laboratory. If you look around here, you can see a lot of tubes and chemicals on the benches and so forth, and these are the things that we use to cut and join DNA and other chemicals in order to regulate gene activity. And then if you come over here, you can see Dr. Morgan Newman, who is actually injecting particular chemicals into zebrafish embryos in order to change their gene activity. And the camera will now show you how she is basically holding the embryos using some tweezers in her left hand and she brings them up to the needle and then under the bench she has a foot pump or a foot switch that actually controls the pressure and injects the chemicals into the embryos.
