DNA Extraction Lab

We recently did a DNA Extraction Lab where we actually made DNA. At first it was crazy on how we made it. First the materials that we needed was wheat, water and alcohol. So first we put a couple of pinches of wheat into a test tube. Then we added hot water. As we added hot water we had to stir it constantly for 5 mins. After we did that we had to add the alcohol. We had to had 14ml of alcohol into the test tube. Then slowly we had to tilt the test tube and add the alcohol slowly into the test tube so the water and alcohol were on there own layer.
After we had to wait about 15 min. While the tube was sitting we can start seeing the DNA start rising up into the alcohol area. We notice somethings about the DNA. It was white and slimy. As for the bottom it was a mucus look like.
Some of the things that I thought were happening was that the alcohol was absorbing the DNA while the wheat and water was separating the cells so that the DNA would show up in the alcohol level.
I couldn't believe that that was what DNA looked like. It was so small. It really didn't look like what we seen in pictures how it looks like a latter but all twisted up. I still can't believe we have that in us just to see what we are made of. Know we know for sure that DNA is in fact really in us.





This is what all the scientist said what DNA looks like, but looking at it the way we made it when we did the lab looks nothing like this.
