1- What is the major idea of the paper? Which technique gave the best result? (2 points)
2- How did they get rid of the soil in the samples (before testing the 4 techniques)? Were they able to get rid of all the soil in the samples (again before testing the 4 techniques)? (3 points)
3- What did they use (enzymatic, chemical or physical or all combined) to extract DNA from the samples in EACH procedure. (12 points)
4- When the DNA was extracted some methods did not lead PCR products. Why was that? (3 points)
