THE MOST BEAUTIFUL EXPERIMENT IN BIOLOGY: Meselson & Stahl, The Semi-Conservative Replication of DNA

In 1958, Matthew Meselson and Frank Stahl published the "most beautiful experiment", where they demonstrated that DNA undergoes semi-conservative replication. In this video, we describe the experiments that lead to this discovery and why understanding how DNA replicates is so important. This video is a complement to Matthew Meselson's iBiology Discovery talk, where Meselson recalls the events that led him to meet Frank Stahl and to plan and execute these experiments.
