How did Hershey and Chase label phage protein?

WebFor this, they cultured bacteriophage in two different media - one containing radioactive sulphur 35S (sulphur being a constituent of certain amino acids) to label the protein coat of the bacteriophage, and another containing radioactive phosphorus to label their DNA core. Hershey and Chase showed that the introduction of deoxyribonuclease (referred to as DNase ), an enzyme that breaks down DNA, into a solution containing the labeled bacteriophages did not introduce any 32 P into the solution. This demonstrated that the phage is resistant to the enzyme while intact.
