Extracting DNA lab conclusion


In science class we extracted DNA from the plant cell and human cell. Deoxyribonucleic acid, also know as DNA, is found in the nucleus, or the control center of a cell. DNA is in nearly every cell and is very small which would make it seem hard to extract, but in fact it is not hard at all. I personally did the extraction of a human cell. To do this is very simple 4 step process. First i took a small amount of Gatorade and swished it in my mouth for one moment. Second, I spit the Gatorade out of my mouth back into the cup and put it into a test tube. Thirdly, i put alcohol in the test tube. Finally, let the test tube, sit at an angle, for fifteen minutes. After letting the test tube sit for fifteen minutes, i found that there were white floating at the top of the mixture that we made. The white pieces floating around is known as DNA. On the other hand, my partner did the plant cell. After doing this lab i learned a lot about DNA and had fun as well.
