Meselson and Stahl were trying to determine if DNA replication was semiconservative, conservative, or dispersive by labeling E. coliDNA with a regimen of heavy nitrogen (H) for one round of replication and then transferring these cells to light nitrogen (L) for two more rounds of replication. Which of the following statements wouldnotbe true within the context of this experiment?a. If DNA replication were conservative, no DNA molecules of intermediate density (H-L) would have been seen. b. If DNA replication were dispersive, only DNA molecules that were of intermediate density (H-L) would have been seen. c. If DNA replication were semiconservative, the DNA molecules that were made would all continue to be heavy density (H-H).d. If DNA replication were semiconservative, the DNA molecules would consist of one parental strand basepaired to one newly replicated strand. e. If DNA replication were semiconserative, a higher proportion of DNA molecules from future divisions would have been low density (L-L)
