WebO experimento Meselson-Stahl Meselson e Stahl conduziram seus famosos experimentos sobre a replicação do DNA usando bactérias E. coli como sistema modelo Eles começaram cultivando E. coli em um meio, ou caldo nutritivo, contendo um isótopo "pesado" de nitrogênio, ^ {15}\text N 15N. WebMeselson and Stahl conducted their research at Caltech. Like Taylor, Meselson and Stahl did not study bacteriophages. Because bacteriophage DNA proved to be very delicate, the researchers worked with the DNA of the bacteria Escherichia coli. Meselson and Stahl labeled DNA with heavy nitrogen isotopes.
