Question

Quizplus · Accepted Answer

The Hershey and Chase blender experiment provided evidence that DNA is the carrier of hereditary information in bacteriophages. Hershey and Chase used two different isotopes (sulfur and phosphorus) to label the protein coat and DNA of the bacteriophage. Only when the DNA was labeled did it get transferred to the host bacteria, indicating that DNA was the substance that carried the genetic material of the virus.
