Oswald Avery
Oswald Theodore Avery (October 21st 1877 - February 2nd 1955) was Chercheur in the field of the Physique and the Médecine. It passed the major part of its career to the Rockefeller Institute Hospital to New York. It was one of the first molecular biologists and a pioneer in immunochimy. Most known of its discoveries in 1944 with his/her collaborators Colin MacLeod and Maclyn McCarty was carried out. They showed that DNA is the molecule which carries hereditary information, and thus that it is the molecule which constitutes the Gène S, in the Chromosome S.
Discovered on the function of the DNA
For that, he works on the bacterial transformation. By treating the substance transforming by specific enzymes Protease, ADNase, it discovers that it is the treatment with ADNase which destroys the transforming principle. The DNA is thus the support of heredity, and not the Protéine S. But it is the Expérience of Harshey and Chase which finishes convincing the scientific community on this point.In his honor, one gave his name to a lunar crater.
