Hershey and Chase performed several experiments to find the chemical nature of the genetic material that is present in all organisms. The graph below shows the results of one such experiment. It tracks the amount of 32P and 35S found in the supernatant after the bacterial cell suspension was agitated in a blender. The Y-axis represents the percentage of radioactivity from 32P and 35S each as compared to all radioactivity detected in the supernatant.
