WebTo determine which model was correct, Matthew Meselson and Franklin Stahl ....... They first grew bacterial cells on medium containing a heavy isotope of nitrogen (15N) . As the cells grew, this form of nitrogen was incorporated into the DNA strands. After several generations, the DNA of these cells contained only the heavy isotope. WebSolution Verified by Toppr Messelson and Stahl proved that DNA replication is semi-conservative in nature. Experiment: Messelson and Stahl used 15N, a heavy isotope of nitrogen while culturing bacteria so that the DNA synthesized is of heavy density. The bacteria were then shifted to 14N medium.
