Web21 apr. 2024 · The enzyme DNA helicase breaks the hydrogen bonds between the bases in a specific region of the DNA molecule. This causes the two strands to separate and unwind, exposing nucleotide bases. The enzyme RNA polymerase binds to the template strand of DNA at the beginning of the sequence to be copied. Web9 jan. 2024 · Helicase, in DNA replication, breaks the hydrogen bonds that hold the double strand together to expose the single strands, in order to kickstart replication. Helicases form a class of enzymes... 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 … buckethead clothing
