A group of scientists is investigating the molecular basis of heredity in fungi. They use a fungal virus and conduct an experiment similar to the Hershey-Chase experiment. They label the DNA of the virus with a radioactive isotope of phosphorus (32P) and the capsid with a radioactive isotope of sulfur (35S). After the virus infects the fungal cells, where should they expect to find the 32P if DNA is the hereditary material?
To understand the mechanism of genetic transfer in viruses, researchers plan to use radioactive labeling. Which combination of radioactive isotopes would best allow them to differentiate between the viral DNA and the capsid protein?
Hershey and Chase concluded that DNA, not protein, is the genetic material based on which of the following evidences?
