I believe the answer is Meselson and Stahl
They developed an experiment to determine how DNA replicates. The experiment tested Watson and Crick's model of replication. They distinguished old DNA and synthesized DNA. Labeled them with isotopes, heavy nitrogen-14 and light nitrogen-14, raised E. coli and spun it. They showed that DNA replicates by a semi-conservative mechanism. Double helix separates and each old strand is a template for the new strand.

Answer: Meselson & Stahl

The two American biologist were Matthew Stanley Meselson and Franklin W. Stahl who are notable for their experimental confirmation of the Watson-Crick theory of the structure and method of replication of deoxyribonucleic acid. They distinguished old DNA and synthesized DNA, which proved that DNA replicates by a semi-conservative mechanism.
