(D) The experimental proof for the semiconservative replication of $DNA$ was first provided by Matthew Meselson and Franklin Stahl in $1958$.They performed their experiments on the bacterium $Escherichia coli$ $(E. coli)$.They grew $E. coli$ in a medium containing $^{15}N$ (a heavy isotope of nitrogen) for many generations, resulting in $DNA$ containing $^{15}N$.Then, they transferred these bacteria to a medium containing $^{14}N$ (a normal isotope of nitrogen).After one generation, the $DNA$ extracted had a hybrid density, and after two generations, it showed both light and hybrid $DNA$, which confirmed the semiconservative mode of $DNA$ replication.

The experimental proof for semiconservative replication of $DNA$ was first shown in a:
