S the enzyme responsible for unwinding dna
WebThe primary enzyme involved in this is DNA polymerase which joins nucleotides to synthesize the new complementary strand. DNA polymerase also proofreads each new DNA strand to make sure that there are no errors. Leading and lagging strands DNA is made differently on the two strands at a replication fork. WebAug 9, 2024 · DNA helicase is an ATP dependent catalytic enzyme which unwinds the dsDNA for providing leading as well as lagging strand replication. It runs ahead of the replication fork and continuously unwinds the dsDNA, providing the template for DNA polymerase to work. Unless DNA helicase unwinds dsDNA, DNA polymerase can not able …
