WebJan 9, 2024 · Helicase breaks the hydrogen bonds forming the double helix structure of DNA. Is DNA a double helix? DNA is composed of two strands that coil around each other to form a double helix. WebHelicase unwinds the helix, and single-strand binding proteins prevent the helix from re-forming. Topoisomerase prevents the DNA from getting too tightly coiled ahead of the replication fork. DNA primase forms an RNA primer, and DNA polymerase extends the …
