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 ...
Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958? Semiconservative ...
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 ...
