Matthew Meselson and Franklin Stahl's 1957 demonstration of DNA replication is considered "the most beautiful experiment in biology." Their density-shift demonstrations not only have stood the test of ...

Each subsequent round of replication would then produce double helices with greater amounts of new DNA. Matthew Meselson and Franklin Stahl were well acquainted with these three predictions ...

A centrifuge was used to separate DNA molecules labeled with isotopes of different densities. This experiment revealed a pattern that supports the semiconservative model of DNA replication.
