We have been learning quite a bit in Biology lately over genetics. Yesterday our lesson was over DNA. We were able to have a hands-on learning lesson. We had a strawberry and decided to extract its DNA. We mixed all of the ingredients to make the extraction solution and then we poured it in a bag with the strawberry. After this we mashed the strawberry until it was a pink juice, we then sieved the liquid away from the chucks over strawberries that were left. When we finished this we poured alchohol into the solution. After about 3 minutes there were bubbles that formed over the top (shown in the picture above).
We took a pair of tweezers and grabbed the center of the bubbles. When we began lifting the tweezers out of the beaker the DNA of the strawberry formed together to make a strand of DNA (show in the picture to the left).
