WitrynaThe Blender experiment has since achieved so much fame that it is almost the only part of the Hershey and Chase paper which is still quoted. WitrynaHere he and Martha Chase did the Hershey-Chase blender experiment that proved that phage DNA, and not protein, was the genetic material. For this, and his body of work on bacteriophage, Hershey shared the 1969 Nobel Prize for Physiology or Medicine with Max Delbr�ck and Salvador Luria.
Hershey and Chase showed that the introduction of deoxyribonuclease (referred to as DNase), an enzyme that breaks down DNA, into a solution containing the labeled bacteriophages did not introduce any 32 P into the solution.
