Answer Bank The Meselson and Stahl experiment starts with E. coli containing 15 N / 15 N labeled DNA grown in 14 N media. Which result did Meselson and Stahl observe by sedimentation equilibrium centrifugation to provide strong evidence for the semiconservative model of DNA replication

The Meselson and Stahl experiment begin with the use of E. coli that has 15 N / 15 N marked DNA grown in 14 N media. Meselson and Stahl noted that the first generation has hybrid 15N/14N DNA, and the second generation possess hybrid 15N/14N DNA and 14N/14N DNA. No 15N/15N DNA was seen in the course of the experiment. The experiment was carried with the use of sedimentation equilibrium centrifugation to give a strong background for the semiconservative model of DNA replication.
