   Meselson and Stahl Experiment gave us the theory of semi-conservative replication of DNA. They have taken E.coli as the model organism and two different isotopes, N-15 and N-14. The N-15 is the heavier isotope, whereas N-14 is the lighter or common isotope of nitrogen.

   14 Μαΐ 2022 · DNA Replication is Semiconservative. The structure of DNA suggested to Watson and Crick the mechanism by which DNA — hence genes — could be copied faithfully. They proposed that when the time came for DNA to be replicated, the two strands of the molecule. separated from each other but.

   Support for the dispersive hypothesis remained strong until proof of semiconservative replication was provided by Meselson and stahl's 1958 paper (pdf). The methods Meselson and Stahl developed allowed them to distinguish existing DNA from newly synthesized DNA and to track new and old DNA over several rounds of replication.
