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.
10 Απρ 2022 · Meselson and Stahl's experiment is a great example of how scientists can obtain evidence to back up a theory about a biological process. Meselson and Stahls' experiment provided unequivocal proof that DNA replicates via semi-conservative DNA replication.
