Nobel Winner Joshua Lederberg Dies

Lederberg (1925-2008) shared the 1958 Nobel Prize for Physiology or Medicine with Edward Tatum and George Beadle. Using E. coli mutants, Lederberg discovered that bacteria conjugate and exchange genes. He also developed the technique of bacterial replica plating in which bacterial colonies can be duplicated onto filters for further analysis.
