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 ...
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 ...
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. These discoveries supported that DNA, rather than ...

That year, they also began working with Alfred Hershey, another phage experimenter. [6] The three would share the 1969 Nobel Prize in Physiology or Medicine , "for work on the replication mechanism and genetics of viruses".)
Surely, someone would have thrown their coat over her, ran to look for water, screamed at her to stop, drop and roll. Found a fire extinguisher.
Martha Cowles Chase (November 30, 1927 – August 8, 2003), also known as Martha C. Epstein, [1] was an American geneticist who in 1952, with Alfred Hershey, experimentally helped to confirm that DNA rather than protein is the genetic material of life.
