Suppose that some cells are grown in culture in the presence of radioactive nucleotides for many generations so that both strands of every DNA molecule include radioactive nucleotides. The cells are then harvested and placed in new media with nucleotides that are not radioactive so that newly synthesized DNA will not be radioactive. What proportion of DNA molecules will still contain radioactivity after two rounds of replication? 1/4 of them will contain radioactivity None of them will contain radioactivity 1/8 of them will contain radioactivity 1/2 of them will contain radioactivity All of them will contain radioactivity
