Overview
The Hershey-Chase experiment, conducted in 1952, was a pivotal study that provided clear evidence that DNA is the genetic material in living organisms. By using bacteriophages, which are viruses that infect bacteria, Hershey and Chase were able to label DNA and proteins with radioactive isotopes. Th...
