What is the Semi Conservative Method of DNA Replication?
What is the Semi Conservative Method of DNA Replication? DNA Replication is semiconservative in nature. The semiconservative nature of DNA replication means that the newly synthesized daughter strands remain associated with their respective parental template strands. Hence the newly formed duplex will consist of an old parental strand paired with the new daughter stand copied from it. Instead, if the two newly synthesized strands together paired themselves to for a new duplex, then it is termed to be ‘conservative’. The process of DNA replication begins at specific sites in the chromosomes termed as the origins of replication. It requires a specific primer bearing a free 3′-OH end, proceeds particularly in the 5′—–>3′ direction on both strands of DNA concurrently. This continuous process results in the copying of the template strands in a semiconservative manner. When the replication process is complete, two DNA molecules which are identical to each other and identical to the origin
