How did Hershey and Chase's use of radiolabeled bacteriophages to study the genetic material validate Avery's research?

• It demonstrated conclusively that the genetic material is not protein.
• It showed that bacteriophages are not digested by bacterial enzymes.
• It proved that bacteria will take up phosphorus, but not sulfur.
• It confirmed that bacteriophages cannot inject radiolabeled DNA.
