The Hershey Phage added to E coli in radioactive medium Chase实验 Demonstrating that DNA. and not Progeny phages become labeled protein, is responsible for direct ing the Labeled phages infect unlabeled bacteria reproduction of phage T2 dur ing the P-o infection of Eco/i. Separation of phage"ghosts"from bacterial cell hage nfected bacteria are labeled with 2p Phage"ghosts" Infected bacteria are unlabeled ViableP-labeled phages are produced Viable unlabeled phages producedThe Hershey￾Chase实验 Demonstrating that DNA, and not protein, is responsible for directing the reproduction of phage T2 during the infection of E.coli
