Pictures from the DNA extraction

Step 1: Combine spinach, water and salt. Blend for 15 seconds on high and the strain the solution.
Add detergent and then let sit for at least 10 minutes. Pour into test tubes, so the tube is about 1/3 full. Add a pinch of enzymes (in this case meat tenderizer).
Gently stir the enzymes and then at isopropyl alcohol so the test tube is now 2/3 full. Let the magic of chemical reactions and density go to work....and voila! DNA.

If you look closely, you will see a white stringy matter floating the in the tube. That's DNA!

Homework (see the post below). D block class, we will be starting early at 12:15/12:20 so you will have time to complete your experiment.
