In Meselson and Stahl’s experiments, bacteria were grown in a medium containing “heavy” nitrogen (15N) and then they were transferred to a medium containing 14N for two additional rounds of replication. The DNA was isolated and centrifuged to separate the DNA strands by weight. Which of the figures below would be expected if the DNA is replicated by a semiconservative mechanism?

In order to determine if DNA pol III can be released and recycled to synthesize multiple Okazaki fragments, an experiment was performed with a donor plasmid, where DNA pol III synthesized a circular fragment, and two possible acceptor plasmids where the DNA pol III could bind if released and recycled. One plasmid contained a primer plus a clamp, the other contained just a primer. The donor and acceptor plasmids are shown below (note that for this portion of the experiment, the B-clamp and primer are on M13Gori plasmid). The result of the experiment was _____.
