WebHershey and Chase started with a virus called a bacteriophage .They used the radioactive isotope sulfur-35 to label the protein of the virus and phosphorus-32 to label the DNA of the virus. They allowed the tagged virus to infect bacteria and studied the results. Hershey and Chase found that the only radioactive isotope within the bacteria was 32P. WebIn the Hershey-Chase experiment, what happened to the bacteria that had been infected by viruses that had radioactive DNA, and to the bacteria that had been infected with viruses that had been marked with radioactive proteins? The bacteria infected with viruses that had radioactive DNA had become radioactive.
