Question

Quizplus · Accepted Answer

Hershey and Chase used sulfur-35 to label protein in the T2 virus and phosphorus-32 to label DNA. In their experiment, they found that only the radioactive sulfur, which was associated with the protein coat of the virus, was transferred to the bacteria during infection. This indicated that the genetic material of the virus was DNA, not protein, and supported the idea that DNA is the genetic material of cells.
