Group 3 – June 13th We are group number 3 and we are going to make a experiment about DNA. First we are going to put in a blender one cup of cold water, the DNA source and a bit of salt, and blend it for about 15 seconds. Then we have to separate the mixture, we have to get 150 ml. . After that we have to put 1/6 of detergent *(aproximately 30 ml.)*. Then we have to shake the mixture. Next we have to let it stand for 10 minutes. Then we have to put the mixture into test tubes *(fill 1/3 of the tube)*. Next we have to put the pineapple juice to each tube. Then we have to shake it slowly so we don´t break the DNA. Next we have to put the alcohol from the wall of the tube until it has 2 equal layers. Finally the DNA will go out of the mixture to the layer of alcohol, and we can put a wood stick to take the DNA out.
