Meselson and Stahl's experiments provided evidence that DNA replication is a semi-conservative process, in which each newly synthesized DNA molecule has one parent strand and one newly synthesized strand. They ruled out the dispersive model and the conservative model, which proposed different mechanisms of DNA replication. They also showed that DNA replication is continuous, not discontinuous.
