WebIn the 1950s, scientists knew very little about DNA beyond its chemical structure. They proposed three different models for how DNA replication occurred: dispersive, semiconservative, and conservative. To tests these hypotheses, Matt Meselson and Frank Stahl devised and conducted an experiment in 1958. WebMatthew Meselson and Franklin Stahl used a density isotope of nitrogen, 15N, to label DNA and density-gradient ultracentrifugation to analyze 15N density-labeled DNA (heavy DNA) before and after rounds of replication in medium contain normal 14N (light nitrogen).
