WebNew DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the 5' to 3' direction. During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging … WebBoth strands of DNA are used in its replication. Since the two strands have polarity and are anti-parallel, one strand can be continuously synthesized (the leading strand) whereas, the other strand is discontinuously synthesized (the lagging strand) which is later stitched together with ligases.
