Meselson-Stahl Experiment

Paul Andersen explains how the Meselson-Stahl experiment was used to prove that DNA copied itself through a semi-conservative process. They grew E. coli in a medium containing heavy nitrogen (N-15). They then added the E. coli to a medium containing regular nitrogen (N-14) and observed it over several generation.
