Answer:
Harshey and chase labeled T2 bacteriophage with radioactive sulfur and radioactive phosphorus. As DNA contains phosphorus, not protein and protein contain sulfur, not phosphorus, therefore, the presence of radioactivity in cell can determine which is the genetic material
.
Then Harshey and Chase infected <em>E.coli</em> with T2 bacteriophage and centrifuged the cell. They found radioactive phosphorus in cell pellet and radioactive sulfur in supernatant.
So by this experiment, they concluded and proved that DNA is the genetic material that gets transfer from one generation to another.
Answer:
DNA is duplicated, or copied
