Vedclass · Answer

(A) The experimental proof for the semi-conservative mode of $DNA$ replication was provided 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,resulting in $DNA$ molecules containing $^{15}N$. When these bacteria were transferred to a medium containing $^{14}N$ (a normal isotope),the $DNA$ extracted after one generation showed an intermediate density,confirming that each new $DNA$ molecule consists of one parental strand and one newly synthesized strand.

Who provided the experimental proof that $DNA$ replicates in a semi-conservative manner?
