WebAlfred D. Hershey and Martha Chase (1952) used radioactive phosphorus (3 2 P) and radioactive sulfur (3 5 S) and showed that when bacteriophage T 2 infects its host cell, Escherichia coli, the phosphorus-containing DNA of the viral particle, not the sulfur-containing protein of the viral coat, enters the host cell and serves the genetic … WebApr 5, 2024 · Hint: This experiment was to prove that DNA is the genetic material and is a factor of heredity that is responsible for carrying the genetic information from one generation to another since it is present inside the nucleus.
