Zinder, Norton (David)

Zinder, Norton (David)
born Nov. 7, 1928, New York, N.Y., U.S.

U.S. biologist.

He received his Ph.D. from the University of Wisconsin. He discovered genetic transduction (the transfer of genes from one type of microorganism to another by an agent such as a bacteriophage) in Salmonella bacteria. Using this transduction, later researchers were able to show that bacterial genes affecting certain physiological processes were grouped together in what are now known as operons. His experiments also led to the discovery of the first bacteriophage that contained RNA as its genetic material.
