Web6 sep. 2024 · Meselson and Stahl could tell from this result that the DNA was being copied in a semi-conservative way. The pattern of two distinct bands—one where a hybrid molecule should be and one where a light molecule should be—is exactly what we’d expect from semi-conservative replication (as illustrated in the diagram below). The Meselson–Stahl experiment is an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative. In semiconservative replication, when the double-stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized. It has been called "the most beautiful experiment in biology." Meselson and Stahl …
