I did not understand HarsheyChase experiment.
Hershey and Chase used T2 phage, a bacteriophage. The phage infects a bacterium by attaching to it and injecting its genetic material into it. This means that the phage’s proteins stayed on the outside of the bacterium. These results showed Hershey and Chase that the genetic material that infects the bacteria is DNA.
