Meselson and Stahl's experiments proved that DNA replicates by which mode? a. conservative b. semi-conservative c. dispersive d. none of the above
Assume that DNA replication in a bacterium occurs via a conservative mode of replication. You conduct a Meselson-Stahl experiment on this DNA. Which of the following results would you observe in a density sedimentation separation of the DNA replication products after FIVE generations?

How did Meselson and Stahl support Watson and Crick's double-helix model? a. They demonstrated that each strand serves as a template for synthesizing a new strand of DNA. b. They showed that the DNA strands break and recombine without losing genetic material. c. They proved that DNA maintains a doublehelix structure while undergoing semiconservative replication. d. They demonstrated that conservative replication maintains the complementary base pairing of each DNA helix.
