class response

during one of our science classes we were extracting DNA from our mouths and a strawberry. it was very interesting and explained itself. in this project a partner takes some gatorade and gurgles it for a minute. they then pour it into a test tube add rubbing alcohol and flips it three or four times. they then set it down for a good fifteen minutes. meanwhile your other partner has a strawberry sample. thaey mix it with a few ingredients and wait for fifteen minutes. after the fifteen minutes are over we looked at our sample and we looked at our samples and saw variations. In my sample it was very clear and you could see tiny strands of DNA floating around. in my partners plant sample it was all a liquid and the DNA was huge. some other peoples where covered in different colors and thatis why we brush our teeth.
