Which of the following statements is true about the Hershey-Chase experiment?
Most or radioactivity was found associated with cell infeted by bacteriophage having radioctive phosphorus.
Proteins contain sulphur but no phosphorus whereas DNA contains phosphorus but no sulphur. Hence, both proteins and DNA can be differentially labelled using radioactive sulphur and phosphorus. Since only DNA enters the bacteria, most of the radioactivity was found in bacteria infected by bacteriophage having radioactive phosphorus.
