Bacteriophage
Hershey and Chase observed that DNA is the identity of the hereditary material in phage T2. Hershey and Chase used radioactive labels to mark the protein of the bacteriaphage in one experiment and the DNA in another.

According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
DNA controls heredity, not proteins.
bacteriophages
Hershey and Chase's experiment worked because they used radioactive labeling to track the DNA and protein separately. This allowed them to determine that only the DNA, not the protein, was passed on to the next generation of bacteria.

Their genetic material
The genetic material is made of DNA.
Their genetic material
The Hershey-Chase experiment was a scientific study conducted in 1952 by Alfred Hershey and Martha Chase. They used bacteriophages, viruses that infect bacteria, to demonstrate that DNA, not protein, is the genetic material that carries hereditary information. The key finding of the experiment was that when the bacteriophages infected bacteria, only the DNA of the virus was injected into the bacterial cell, not the protein coat. This provided strong evidence that DNA is the molecule responsible for transmitting genetic information.
The Hershey-Chase experiment disproved proteins as the physical carrier of inheritance and instead provided evidence that DNA is the primary molecule responsible for transmitting genetic information.
