Thus, the Hershey–Chase experiment helped to confirm that DNA, not protein, is the genetic material. [6] 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. This ...

Hershey was born in Owosso, Michigan to Robert Day and Alma Wilbur Hershey. He earned a B.S. in chemistry in 1930, and Ph.D. in bacteriology in 1934 from Michigan State University. Shortly after, Hershey accepted a faculty position at Washington University in St. Louis, [1] [2] serving as an instructor of bacteriology and immunology from 1934 ...

Hershey–Chase experiment. Confirmation that DNA is the genetic material which is cause of infection came from the Hershey–Chase experiment. They used E.coli and bacteriophage for the experiment. This experiment is also known as blender experiment, as kitchen blender was used as a major piece of apparatus.
In 1944, Oswald Avery, working at the Rockefeller Institute of New York, demonstrated that genes are made up of DNA [3] (see Avery–MacLeod–McCarty experiment). In 1952, Alfred Hershey and Martha Chase confirmed that the genetic material of the bacteriophage, the virus which infects bacteria, is made up of DNA [4] (see Hershey–Chase ...
Experiments conducted in 1952 by Alfred Hershey and Martha Chase demonstrated how the DNA of viruses is injected into the bacterial cells, while most of the viral proteins remain outside. [ 1 ] [ 2 ] The injected DNA molecules cause the bacterial cells to produce more viral DNA and proteins.
