In 1953, Watson and Crick proposed a double-helical structure for DNA and suggested that it replicated in a semi-conservative manner. This method of replication was not universally accepted as correct, however. In this talk, Meselson recalls the events that led him to meet Frank Stahl and to plan and execute the now famous experiment proving that DNA does indeed undergo semi-conservative replication.

About the Speaker
Dr. Meselson has made important contributions to the areas of DNA replication, repair and recombination as well as isolating the first restriction enzyme. Currently, he is Professor of Molecular and Cellular Biology at Harvard University where his lab studies aging in the model organism bdelloid rotifers. Meselson is also a long time advocate for the abolition of biological and chemical weapons. He has received many honors including a Lasker Award in 2004.
