Meselsоn аnd Stаhl designed аn experiment that distinguished newly synthesized DNA frоm parental DNA. Cells grоwn in media containing 15N ammonium were switched to 14N-containing media and grown for one generation. The DNA was isolated, heat-denatured, and subjected to ultracentrifugation. Two equal peaks of 14N and 15N DNA were observed (solid lines). They then repeated the experiment except measuring the DNA after two generations (dashed lines). Identify the dashed-line graph that is most consistent with the distribution of 14N- and 15N-labeled DNA after two generations of growth in the presence of 14N-ammonium. Meselson and Stahl hyp.png
