This document provides instructions for extracting DNA from dried split peas. It explains that blending the peas breaks open the pea cells. Dishwashing detergent is then added to break apart the cell and nuclear membranes, releasing the DNA. Meat tenderizer contains enzymes that break apart surrounding proteins to further isolate the DNA. Finally, a layer of isopropyl alcohol is added, causing the DNA to float to the top and be separated from the mixture.
