" Messelson and stahl used this element to prove semi conservative method of DNA replication in E Coli "

Mode of DNA replication in E. coli is :

Mode of DNA replication in E. coli is :-

Mode of DNA replication in E. coil is

the usual method of DNA replication is

First experimental proof for semi-conservative DNA replication was shown in

“Use of heavy isotope of nitrogen by Meselson and Stahl demonstrated semi-conservative mode of replication of a DNA molecule.” Explain how did they arrive at this conclusion.

In the experiment conducted by Meselson and Stahl using heavy 15N to prove semi-conservative nature of DNA, the first generation was found to have
