The Hershey-Chase experiment was conducted in 1952 by scientists Alfred Hershey and Martha Chase. They used a bacteriophage, a virus that infects bacteria, to investigate whether genetic material is made of DNA or protein. They labeled the DNA of the bacteriophage with radioactive phosphorus and the protein coat with radioactive sulfur. After infecting the bacteria with the labeled bacteriophages, they found that only the radioactive DNA was transferred into the bacteria, proving that DNA, not protein, is the genetic material. This experiment provided crucial evidence supporting the idea that DNA is the molecule responsible for carrying genetic information. **
