Text Solution

Verified by Experts

The correct Answer is:
B
DNA replication is semi- conservative that means DNA formed after replication contains one strand of its parent DNA and this was proved by Meselson and Stahl [1958].
During replication the strand formed in leading strand is continuous , while the strand formed in lagging strand is discontinuous in the small pieces (Okazaki fragments).
