Explanation:

In 1952, Alfred Hershey and Martha Chase conducted experiments using bacteriophages (viruses that infect bacteria). They labeled the DNA of bacteriophages with radioactive phosphorus (\(^{32}\)P) and the proteins with radioactive sulfur (\(^{35}\)S). When the bacteriophages infected bacteria, only the \(^{32}\)P - labeled DNA entered the bacteria, while the \(^{35}\)S - labeled proteins remained outside. This demonstrated that DNA, not protein, was the genetic material being inherited.

Answer:

Chase and Hershey
