Meselson and Stahl's experiment proved the semi- conservation mode of DNA replication . Explain .

Describe Meselson’s and Stahl’s experiment to explain semiconservative mode of replication.

State the uses of isotopes

“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

Semiconservative DNA replication was first demonstrated by
