Analyze and Conclude 1. Evaluate How did the properties of the DNA you observed compare to those you
predicted in Pre-Lab Question 3?

2. Infer Why do you think that most DNA is stored in the nucleus of a cell and not
in the cytoplasm?

3. Use Analogies Sewing thread is very thin and difficult to see once a length of
thread is removed from its spool. How is the thread and spool an analogy for
what happened to the DNA in Step 7.

4. Draw Conclusions Water is the main ingredient in the detergent solution.
Ethanol is a type of alcohol. What can you conclude about the solubility of DNA
in water and alcohol?

5. Predict Do you think it would be easier or harder to extract DNA from animal
cells than from plant cells? Explain your answer?
