Hershey and Chase concluded that is the hereditary molecule by examining how radioactively labeled molecules moved between a virus and bacteria.

Question

Quizplus · Accepted Answer

Hershey and Chase used radioactive labeling to show that DNA is the hereditary molecule. They labeled the DNA of a virus with radioactive phosphorus and the proteins of the virus with radioactive sulfur. They then infected bacteria with the virus and found that the radioactive phosphorus was transferred to the bacteria, while the radioactive sulfur was not. This showed that DNA, not protein, was the hereditary molecule.
