DNA. bacteriophage. A.D. Hershey (born Dec. 4, 1908, Owosso, Mich., U.S.—died May 22, 1997, Syosset, N.Y.) was an American biologist who, along with Max Delbrück and Salvador Luria, won the Nobel Prize for Physiology or Medicine in 1969. The prize was given for research done on bacteriophages (viruses that infect bacteria).

( b. 4 December 1908 in Owosso, Michigan; d. 22 May 1997 in Syosset, New York ), Nobel Prize –winning bacteriologist, biochemist, and molecular geneticist whose work with bacteriophages helped prove that DNA is the source of heredity, thus paving the way to an understanding of viral infections.
Apr 29, 2019 · Hershey, A. D. (Alfred Day), 1908-. During the twentieth century in the United States, Alfred Day Hershey studied phages, or viruses that infect bacteria, and experimentally verified that genes were made of deoxyribonucleic acid, or DNA. Genes are molecular, heritable instructions for how an organism develops.
The DNA of the virus was tagged with radioactive phosphorus in one experiment, and this ended up in the pellet. The protein shell of the virus was tagged with radioactive sulphur, and this ended up in the supernatant. The heavier bacterial cells formed the pellet, so Hershey and Chase knew that DNA was the genetic material of the virus, as the ...
