Question

2. What did the DNA look like? Relate what you know about the chemical structure of DNA to what you observed today. 3. Explain what happened in the final step when you added ethanol to your strawberry extract. (Hint: DNA is soluble in water, but not in ethanol) 4. A person cannot see a single cotton thread 100 feet away, but if you wound thousands of threads together into a rope, it would be visible much further away. Is this statement analogous to our DNA extraction? Explain. 5. Why is it important for scientists to be able to remove DNA from an organism? List two reasons. 6. Is there DNA in your food? __________ How do you know?
