DNA Replication As the genetic information, DNA must be faithfully replicated and passed down to the next generation The structure of DNA immediately suggested a replication mechanism A strand of DNA can serve as a template for replication If you know one strand, you can determine the other What is the mechanism of replication? Meselson & Stahl used density centrifugation biomolecules will float or sink until they reach the point at which their density equals that of the gradient Meselson and Stahl?s results did not support the conservative replication model Using the same approach as Meselson and Stahl, how could you distinguish between these models?
