Matt Meselson and Frank Stahl share the story of their groundbreaking experiment from 1958 that definitively showed semiconservative DNA replication. • 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. • 0:00 Introduction • 2:01 The Spark • 4:14 The Very Beginning • 5:23 A Gorgeous Insight • 7:59 Serendipity • 9:45 Three Targets • 14:36 That’s Replication • 17:49 The Fundamental Things • 20:27 Epilogue and Credits • Scientist Biographies: • Matthew Meselson: 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. • Frank Stahl: Frank Stahl received his PhD at the University of Rochester, where he studied genetic recombination in phage. He performed postdoctoral studies at Caltech, during which he completed the famous Meselson-Stahl experiment, and joined the faculty at the University of Oregon in Eugene in 1959. He is now an emeritus faculty member who enjoys teaching and family life, and the natural wonders of Oregon. • Additional Resources: • More info at our website https://www.ibiology.org/genetics-and... • See the Explorer’s Guide to Biology for a first-person and in-depth description of Meselson and Stahl’s studies, as well as educational resources associated with their foundational key experiment: • https://explorebiology.org/summary/ge... • Credits: • Elliot Kirschner (Wonder Collaborative): Executive Producer • Shannon Behrman (iBiology): Executive Producer • Brittany Anderton (iBiology): Producer • Derek Reich (ZooPrax Productions): Videographer • Eric Kornblum (iBiology): Videographer • Rebecca Ellsworth (The Edit Center): Editor • Adam Bolt (The Edit Center): Editor • Gb Kim (Explorer’s Guide to Biology): Illustrations • Chris George: Design and Graphics • Maggie Hubbard: Design and Graphics • Marcus Bagala: Original music • Samuel Bagala: Original music • #scientist #science #scientists #dnareplication
