Today, we began our actual experiment by extracting DNA from 5 different brands of cereal. The process starting by picking out a small piece of cereal which to get DNA from. That small chunk was put into a 2mL tube that already contained 500ul of a 1% saline solution and was vortexed with a mini-pestle for about 2 minutes. The tube was then centrifuged for 2 minutes to get the chunks on the bottom of the tube. It was again vortexed again with the mini-pestle until the solution was a liquid. Then 100μl of the cereal solution was added to a tube containing 300μl of chelex. The new tube was vortexed for around 1 minute and placed in a hot bath at 95 degrees C for 10 minutes. The final steps were to centrifuge the tube for 2 minutes and then take 50μl of the supernatant in a new tube. This process was repeated for each of the 5 brands of cereal used in the experiment.
