How is dna unzipped
WebHow is DNA unzipped? The first step in DNA replication is to separate or unzip the two strands of the double helix. The enzyme in charge of this is called a helicase (because it unwinds the helix). The point where the double helix is opened up and the DNA is copied is called a replication fork. What causes DNA to unwind? Web28 aug. 2024 · The unzipping exposes the bases on the DNA strands and enables free-floating nucleotides to pair up with their complementary bases. DNA polymerases …
