Extracting DNA was exciting for me. Especially to see how the food we eat has DNA just like us. The way we got the DNA out of the strawberry was to first make sure we crushed it in a plastic bag. We then added detergent and salt inside the plastic bag. Since we had to do the activity with a partner, my partner shook the bag so it would be even and without bubbles. My partner grabbed the beaker, she put the coffee strainer inside, without breaking it. This acted as a strainer when straining spaghetti. Then we poured the strawberry mixture into the coffee strainer and did it until we got a certain amount of liquid. Then we added cold, rubbing alcohol, slowly. The coolest part of the whole activity was stir the white strings with a coffee stirrer and take it out. The white cloudy strings that we took out was the DNA. To have as a treat we even got to keep the DNA. -Vanessa Vargas
