Witryna• Hershey and Chase established whether the phage injected DNA or protein into host bacteria. They prepared two samples of phage: ³⁵S, which labels protein and ³²P, which labels DNA. It was found that only ³²P entered the bacterial cells, indicating that DNA, not protein, is the genetic material.
