    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. Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. CsCl density gradient centrifugation Process used by Meselson and Stahl for studying semiconservative replication of DNA was CsCl density gradient centrifugation. How did Meselson and Stahl distinguish between semiconservative and dispersive replication in their experiment? After one round of replication, both heavy and light DNA single strands were present in alkaline gradients. ... Replication initiates from a single origin, creating a single replication bubble in the plasmid.
