Question

Quizplus · Accepted Answer

Meselson and Stahl's experiment involved growing bacteria in a medium containing heavy nitrogen (15N) and then transferring them to a medium containing light nitrogen (14N). They observed the distribution of different-weighted DNA over multiple generations of bacteria and showed that DNA replication is semiconservative. The experiment did not involve proteases, nucleases, or political ideologies.
