Write a note on the semi-conservative mode of DNA replication.
The semi-conservative model of DNA replication hypothesized by Watson and Crick was based upon the property that during replication, the two strands would separate and act as a template for the synthesis of new complementary strands. After the completion of replication, each DNA molecule would have one parental and one newly synthesized strand. This scheme was termed as ‘Semi-conservative’ DNA replication.
