How did hershey and chase use radioactivity

WebHershey and Chase experimented with radioactively labeled phosphorus and sulphur to determine that DNA and not protein is the genetic material. Which of the following was essential to this confirming experiment? A Sulphur is present in amino acids in the protein coat of bacteria B Phosphorus is present in high amounts in DNA C WebHershey and Chase labeled one batch of phage with radioactive sulfur, 35 S, to label the protein coat. Another batch of phage were labeled with radioactive phosphorus, 32 P. Because phosphorous is found in DNA, but not protein, the DNA and not the protein would be tagged with radioactive phosphorus.
