Hershey and Chase used radioactive ³⁵S and ³²P in experiments to provide evidence that DNA is the genetic material. These experiments pointed to DNA because A) progeny viruses retained ³²P but not ³⁵S. B) the presence of ³²P in progeny viruses indicated that DNA was passed on. C) the absence of ³⁵S in progeny viruses indicated that proteins were not passed on. D) ³²P indicated where the DNA label was localized. E) All of the above
