Instructions:
1. Place a bottle of isopropyl alcohol into the freezer for later use. Next, pour 90mL of water in a glass container.

5. Pour the extraction mixture into the bag with the strawberry.

6. Remove as much air from the bag as possible and ensure that it is properly sealed.

7. Using your fingers, squish the strawberry inside of the bag until there are no large pieces remaining.

8. Pour the strawberry mixture through a strainer and allow it to drip into a glass below. Use a spoon to help force more of the mixture through the strainer.

9. Transfer the liquid into a smaller glass container (roughly 50-100mL in size) to help isolate the DNA on the surface of the mixture.

10. Add 1 tsp (5mL) of the chilled isopropyl alcohol to the liquid and hold it up to eye level. The white layer on the top of the container is the DNA separating from the rest of the liquid!

11. Use tweezers to remove the DNA from the container and place it on a dish to examine.
