Text Solution

Verified by Experts

The correct Answer is:
B
The experimental proof for semiconservative replication of DNA was first shown in a bacterium , Escherichia coli . It was discovered by Meselson and Stahl (1958).

In this mode of replication , one strand of parent DNA is conserved in the progeny while the second is freshly synthesised . Meselson and Stahl proved this by using heavy isotope of Nitrogen `(N^(15))` .
