Phosphorous 32 was used to label the Nucleic Acid.  Sulfur 35 was used to label the protein.  The progeny of the E. coli cells Hershey and Chase grew the virus in had Phosphorous 32 in them which concluded that the DNA went inside and was the genetic material.  The phage coating left on the outside tested positive for Sulfur 35 which meant protein was left on the outside.


If they had just used one substance, they wouldnt be able to be completely sure what was going on with the other molecules they were tracing.
