1. In what organelles is plant DNA located?
2. What molecules or structures are present in cell that might
interfere with DNA extraction?
3. Why do you also perform analysis on food that is verified
to be a non-GMO food?
4. Why do you preform two separate PCR reactions on each
DNA sample?

5. What is the purpose of the GMO-positive control DNA in the experiment?



6. Why would you resolve your PCR products by electrophoresis?

7. If you ran this experiment, predict what you expect in each lane. Type in your response into the table for each lane (yes, no, or don’t know).
