Question

Explain Meselson and Stahl’s experiment to prove semiconservative DNA replication.

Answer 1

The Meselson and Stahl ExperimentDescribed. Meselson and Stahl tested the hypothesis of DNA replication. ... 15N is a heavy isotope of nitrogen so the DNAsynthesized is of heavy density. They then shifted the bacteria to a 14N medium, DNAwas isolated at different times corresponding to replication cycles 0, 1, and 2.

The Meselson and Stahl Experiment Described Meselson and Stahl tested the hypothesis of DNA replication. ... 15N is a heavy isotope of nitrogen so the DNA synthesized is of heavy density. They then shifted the bacteria to a 14N medium, DNA was isolated at different times corresponding to replication cycles 0, 1, and 2.
