Quizplus · Accepted Answer

Diagram B shows the amino acid histidine, which was used by Hershey and Chase in their experiment to label the protein component of T2 bacteriophages. The experiment aimed to determine whether DNA or protein was responsible for carrying genetic information in viruses. By using radioactive sulfur to label the protein and radioactive phosphorous to label the DNA, they were able to show that only the DNA entered the bacterial host and replicated, indicating that DNA, not protein, was the genetic material.
