How to Extract DNA from a Strawberry






1. First we put the strawberry and a buffer in a plastic bag a squished it until it look like pulp (like the picture below).
2. Next we put the pulp into the funnel in order to only the liquid part of the pulp.
3. After there was enough of the liquid in the test tube, we put chilled alcohol into the test tube.

 4. Then, we let the alcohol sit for a couple minutes and eventually we could see the DNA floating around on top of the original liquid. The DNA looked very white and was just resting in the liquid. Below is a before and after picture of how the liquid looked before and after then alcohol had been in the liquid for awhile.


5. After the DNA began to show in the liquid, we were able to extract the DNA out of the liquid using a special tool. Below is a picture of the DNA we extracted.
