In 1962, he moved college, he spent a year in Ossining, New York, at to the Salk Institute in La Jolla, California, where the Holbrook Military Academy, where he taught he discovered the interaction between DNA tumor mathematics and science and was in charge of the viruses and the genetic material of cultivated cells. athletic program.

As an aside, after Benacerraf assumed Murphy of the United States. his position as chairman of pathology, he discarded the gross and microscopic teaching sets that had 198 Annals of Clinical & Laboratory Science, vol. 39, no. 2, 2009 been accumulated for medical students by his It was there, in 1979, that Warren first noticed illustrious predecessors. Benacerraf received the small curved bacteria in gastric biopsies. Over the 1980 Nobel Prize in Physiology or Medicine for his next 2 years he demonstrated that the organisms discovery, while at New York University, of the were usually related to chronic gastritis and ulcers immune response genes.
