The alcohol will float to the top. 10. Look at the layer where the alcohol meets the water- you will see white stringy stuff 11. Place the straw or toothpick inside the test tube and twirl it around and watch the DNA “twirl” around the rod. Well done! You have just isolated DNA! 12. Thoroughly clean and save the plastic spoon, rubber band, beakers, and test tube. Throw away the baggies, mashed fruit, DNA, and tooth picks/straw. Conclusions: 1. What did mashing do to the fruit cells? 2. Since Dawn’s ad slogan use to be, “Dawn takes grease out of your way!” what do you think the detergent did to the cells? (hints: What organic molecule is grease? What predominant cell part is madeo f this organic molecule? Whatother molecules are rpesent in this cell part?) 3. What is being filtered out? 4. What goes through the filter? 5. What does the alcohol do? (hint: What organic molecule are be trying to extract?) 6. Why is the alcohol able to layer on top of the detergent and fuit cell solution. Why? 7. EXPLORE: What is DNA used for when it is extracted?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
