Using a bacteriophage (virus) and the bacterium Escherichia coli, Hershey and Chase were able to show that only viral DNA entered the host; thus it was DNA that directed the production of new viral particles. This strongly suggested that DNA was the genetic material. 1  Take a tour of the Hershey-Chase Experiment.
Francis Harry Compton Crick OM FRS was a British molecular biologist, biophysicist, and neuroscientist, most noted for being a co-discoverer of the structure of the DNA molecule in 1953 with James Watson, work which was based partly on fundamental studies done by Rosalind Franklin, Raymond Gosling and Maurice Wilkins. Together with Watson and Wilkins, he was jointly awarded the 1962 Nobel Prize in Physiology or Medicine for their discoveries concerning the molecular structure of nucleic acids a
