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. FURTHER ...
He and a colleague proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA’s helical structure. By Delthia Ricks Franklin W. Stahl, a molecular biologist ...
Franklin W. Stahl, an American molecular biologist whose landmark 1957-58 experiment with colleague Matthew Meselson revealed how DNA replicates, helping pave the way for a revolution in genetics ...
Older DNA strands are preferentially sorted into stem cells when they self-renew (A). This segregates the DNA most recently replicated, and therefore most error-prone, into cells destined for ...
