How is dna unzipped at the replication forks? DNA replication occurs through the help of several enzymes. These enzymes “unzip” DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created.
How 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). … Once the strands are separated, an enzyme called DNA polymerase copies each strand using the base-pairing rule.
What unzips DNA for replication? The helicase unzips the double-stranded DNA for replication, making a forked structure.
