Solution
The experiment which shows that DNA is the genetic material in bacteriophages is the Hershey-Chase experiment.
Explanation:
Hershey and Chase labelled T2 bacteriophage DNA with radioactive phosphorus (32P) and phage protein with radioactive sulfur (35S). After infection of bacteria, only the 32P label entered the bacterial cells and was found in progeny phages, while 35S stayed outside, showing that DNA (not protein) carries the genetic information.
