(D) Matthew Meselson and Franklin Stahl performed an experiment in $1958$ using $E. coli$ to prove the mode of $DNA$ replication.They used heavy isotope $^{15}N$ and light isotope $^{14}N$ to label the $DNA$ strands.After several generations,they observed that the $DNA$ molecules contained one heavy strand and one light strand,which confirmed that $DNA$ replication is semi-conservative,meaning each new $DNA$ molecule consists of one parental strand and one newly synthesized strand.
