Question

Meselson and Stahl's experiments provided evidence that DNA replication is semi-conservative, meaning that each strand of the original DNA molecule serves as a template for the synthesis of a new complementary strand, resulting in two daughter DNA molecules, each with one original and one newly synthesized strand. Their experiments ruled out the possibilities of conservative and dispersive models of DNA replication.
