That left the scientists with only two options: either DNA replicated semiconservatively, as Watson and Crick had predicted, or it replicated dispersively. To differentiate between the two, Meselson and Stahl had to let the cells divide again and then sample the DNA after a second round of replication.
Meselson and Stahl confirmed the DNA replication is semiconservative when they found only hybrid (intermediate density) DNA in bacteria after first growing them in a medium with heavy nitrogen and then switching them to a light nitrogen.
