Yay! We finally got to do the ever popular extracting DNA from a strawberry experiment. For those of you who don't know how to do this here is a blow by blow.
Preparation: put a strawberry and some rubbing alcohol in the freezer over night.
First off get a plastic ziplock bag and add the frozen strawberry, 5ml of dish soap, 2.5ml of salt and 25ml of water.
Seal the bag and start crushing everything together. This part was super fun. L crushed for about 5 minutes.
Cut a small hole in the corner of your bag and pour your solution into a test tube about half way.
Then add the ice cold rubbing alcohol until the test tube is 3/4 full and watch the magic happen! You can see the DNA separating. L was super excited.
Carefully extract a strand from the solution. L placed it in a petrie dish but later moved it onto a slide for further investigation.
How cool to check it out under the microscope. I had to explain to L that we wouldn't actually be able to see the double helix since we just have your average microscope and we'd need nanotechnology for that. She still though what we could see was pretty cool.
