The first thing that happens is a replication structure binds to the DNA molecule. This is usually a signalling molecule or some type of protein. Next, this replication structure attracts DNA helicase enzymes which "unzip" the double stranded helix.
During transcription, the enzyme RNA polymerase opens the DNA double helix to expose a segment of the DNA that will be transcribed into RNA.
Helicase attaches to the DNA strand at the replication fork, which is the region where the double-stranded DNA is unwound to separate the two strands during DNA replication. Helicase helps to unzip the double helix by breaking hydrogen bonds between the base pairs.
DNA replication is a process where the double-stranded DNA molecule is unwound, or unzipped, by enzymes called helicases. This unwinding allows for the separation of the two parental DNA strands, which then serve as templates for the synthesis of new DNA strands.

DNA helicase is the enzyme responsible for unzipping the double-stranded DNA during processes like replication, transcription, and repair. DNA helicase works by breaking the hydrogen bonds between the two strands of DNA, allowing the DNA to separate and expose the nucleotide bases for replication or transcription to occur.

the one that breaks it is called Helicase and the one that adds it is called Polymerase.
DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication). DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.

one of them is heliocase. it 'unzips' the DNA strand. You can always remember this because it's in a popular joke: Q. Why is the enzyme heliocase a lot like a teenage boy? A. They both want to unzip your jeans (genes) !!!!!
