The Hershey-Chase experiments were a series of experiments conducted by Alfred Hershey and Martha Chase in 1952. The experiments were designed to determine whether DNA or protein was the genetic material of bacteriophages. In the experiments, bacteriophages were labeled with either radioactive phosphorus (32P) or radioactive sulfur (35S). The 32P label was incorporated into the DNA of the bacteriophages, while the 35S label was incorporated into the protein coat of the bacteriophages. The bacteriophages were then allowed to infect bacteria, and the bacteria were then lysed. The results of the experiments showed that only the 32P label was present in the bacteria, indicating that the DNA of the bacteriophages was the genetic material.
