The Hershey-Chase Experiment

Part A
This is a T2 phage, a type of phage that infects E. coli.
Part B
Hershey and Chase did a series of classic experiments demonstrating that DNA is the genetic material of the T2 phage.
Part C
The T2 phage consists of a protein coat and DNA. It is the DNA that contains P.
Part D
Hershey and Chase used radioactive sulfur to label the phage's proteins.
Part E
Since the phage DNA entered the infected cell, it makes sense that DNA is the genetic material.
