Vedclass · Answer

(C) The semiconservative mode of $DNA$ replication was experimentally proven by Matthew Meselson and Franklin Stahl in $1958$. They grew $E. coli$ in a medium containing $^{15}N$ (a heavy isotope of nitrogen) for many generations to incorporate it into the $DNA$. Then,they transferred these cells to a medium containing $^{14}N$ (a normal isotope). After one generation,the $DNA$ extracted showed a hybrid density,and after two generations,it showed both light and hybrid $DNA$,confirming the semiconservative nature of replication.

$DNA$ replicates semiconservatively. This was experimentally proven by:
