The scientists also examined the now bacteriophages produced after infection. Based on the graph, which isotope(s), if any, appeared in these new bacteriophages?
Use the passage to answer the question
In 1952, Alfred Hershey and Martha Chase conducted an experiment about bacteriophage reproduction They inserted a phosphorous isotope (P) into the bacteriophages DNA, and a sulfur isotope (5) into a protein in the bacteriophages capsias Hershey and Chase then infected bacteria with the bactenophages After infection, they put the bacteria in a blender to separate the cells from the extracellular matter. They measured the percentage of isotopes that remained in the extracellular matter. The results are in the graph below
