About this Talk
In 1958, Matthew Meselson and Frank Stahl published the "most beautiful experiment" in biology, where they demonstrated that DNA undergoes semi-conservative replication. In this video, Youreka Science describes the experiments that led 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.

About Youreka Science
Youreka Science was created by Florie Charles, a cancer researcher at UCSF. While teaching 5th graders about the structure of a cell, Charles realized the importance of incorporating scientific findings into classroom in an easy-to-understand way. From that she started creating whiteboard drawings that explained recent papers in the scientific literature to the general public. Charles has created over twenty videos about the latest scientific experiments and is now joined by Alex Olson to produce more fun and engaging videos. Learn more at http://yourekascience.org/.
