The inducing substance, on the basis of its chemical and physical properties, appears to be a highly polymerized and viscous form of sodium desoxyribonucleate. Among microorganisms the most striking example of inheritable and specific alterations in cell structure and function that can be experimentally induced and are reproducible under well defined and adequately controlled conditions is the transformation of specific types of Pneumococcus. Oswald Avery, in full Oswald Theodore Avery, (born October 21, 1877, Halifax, Nova Scotia, Canada—died February 20, 1955, Nashville, Tennessee, U.S.), Canadian-born American bacteriologist whose research helped ascertain that DNA is the substance responsible for heredity, thus laying the foundation for the new science of molecular genetics.His work also contributed to the understanding … Among microorganisms the most striking example of inheritable and specific alterations in cell structure and function that can be experimentally induced and are reproducible under well defined and adequately controlled conditions is the transformation of specific types of Pneumococcus.

Oswald Avery quotes relating to dozens of different topics that are waiting to be discovered. The experimental data presented in this paper strongly suggest that nucleic acids, at least those of the desoxyribose type, possess different specificities as evidenced by the selective action of the transforming principle. That is why Mendel's definition of the gene as the unvarying bearer of hereditary traits, its chemical identification by Avery (confirmed by Hershey), and the elucidation by Watson and Crick of the structural basis of its replicative invariance, are without any doubt the most important discoveries ever made in biology.

Oswald Theodore Avery (1877-1955) was a distinguished Canadian-born bacteriologist and research physician and one of the founders of immunochemistry. Thus, it is evident that the inducing substance and the substance produced in turn are chemically distinct and biologically specific in their action and that both are requisite in determining the type of specificity of the cell of which they form a part.
