Describe the Meselson-Stahl experiment in which three hypotheses of DNA replication were tested. Which of the three hypotheses was supported by evidence collected? Semiconservative was the hypotheses that was supported.

Step 1
The experiment involved growing E. coli bacteria in a medium containing a heavy isotope of nitrogen, $^{15}N$, and then transferring the bacteria to a medium containing a lighter isotope, $^{14}N$. The DNA was then extracted and analyzed using density gradient Show more…

In the Meselson-Stahl experiment that established the semiconservative nature of DNA replication, the extraction method produced short fragments of DNA. What sort of results might have been obtained with longer pieces of DNA?
