Answer:
The correct answer is- phosphorus and sulfur
Explanation:
Hershey and Chase used radioactive phosphorus and sulfur to label T2 bacteriophage. Then they infected E.coli with these bacteriophage labeled with radioactive phosphorus and sulfur.
After infection, they centrifuge the cell and found that radioactive phosphorus is present in the bottom and radioactive sulfur in supernatant . As sulfur is mostly the part of protein not DNA and is found in supernatant and phosphorus is mostly present in DNA not protein which was found in cell debris, therefore, it was proved that DNA is the genetic material.
