About this talk
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.
