How to Extract DNA from Strawberries


Here is a little How-to list of how to extract DNA from strawberries. You will need a test tube, a plastic bag, a coffee filter paper, a pipette, DNA extraction buffer and icy cold isopropyl alcohol.



1. First, grab a strawberry and place it inside a plastic bag. Squish the strawberry to a pulp




2. Then fill a test tube a quarter full with DNA extraction buffer (soapy salty water) and pour it's contents into the plastic bag



3. Mix the buffer and smashed strawberries 



4. Grab another test tube and place a coffee filter paper at the top of the tube.
5. Strain the strawberry through the the coffee filter paper so that the liquid drips to the bottom of the test tube



6. When enough liquid has reached the bottom of the test tube, throw away the coffee filter paper and the strawberries.
7. With you test tube with the strawberry liquid, fill it with some ice cold isopropyl alcohol by pipetting it down the side of the tube 
8. Wait a couple minutes and you should begin to see the DNA begin to form



9. Use something to pull the DNA out of the the bottom of the test tube and witness this amazing phenomenon!
