DNA Synthesis: Process, Importance and Direction

WebDNA is read by DNA polymerase in the 3′ to 5′ direction, meaning the new strand is synthesized in the 5' to 3' direction. Since the leading and lagging strand templates are oriented in opposite directions at the replication fork, a major issue is how to achieve synthesis of new lagging strand DNA, whose direction of synthesis is opposite to the … WebDNA polymerase synthesizes DNA in the 5' to 3' direction on the leading strand.
