Matt Meselson and Frank Stahl were in their mid-20s when they performed what is now recognized as one of the most beautiful experiments in modern biology. In this short film, Matt and Frank share how they devised the groundbreaking experiment that proved semiconservative DNA replication, what it was like to see the results for the first time, and how it felt to be at the forefront of molecular biology research in the 1950s. This film celebrates a lifelong friendship, a shared love of science, and the serendipity that can lead to foundational discoveries about the living world.
