Solution
The correct option is B Hershey and Chase
Hershey and chase used differential labels (35-sulphur and 32-phosphorous) to label proteins and nucleotides of bacteriophages. Using these differentially labeled bacteriophages, Hershey and Chase were able to prove that the radioactivity status of progeny virus particles produced is dependent on the nucleic acid and not protein. Thus DNA is the genetic material. They were awarded a nobel prize for providing conclusive evidence that DNA is the genetic material.So, the correct answer is option D.
