In the fаmоus Hershey-Chаse experiment, а virus was used tо determine the heritable substance оf life. Hershey and Chase generated two batches of bacteriophage viruses; one with radioactive sulfur (S35) in its proteins, the other with radioactive phosphorus (P32) in its DNA. E. coli bacteria was then exposed to and infected by these phage batches. After a period of time, the bacteria were agitated using a blender to shake off the viruses, then they were separate the bacterial pellet from the supernatant. At the end of the centrifugation, the supernatant was sampled and the results are displayed in the graph, below. The horizontal axis is labeled Running Time in Blender and ranges from 1 to 22. The vertical axis is labeled percent of Total and ranges from 0 to 120. Three lines are shown with different colors and labels in the legend on the right. The red line labeled Infected Bacteria starts at 100 and gradually decreases to approximately 90. The green line labeled Extracellular S35 starts near 0, rises steeply between time 1 and 4 to reach approximately 80, then levels off and remains nearly flat for the rest of the time period. The purple line labeled Extracellular P32 starts at approximately 20 and gradually increases to approximately 25, remaining relatively flat throughout. How does this data support the claim that DNA is the source of heritable information?
