WebSolution. DNA helicase is responsible for opening up our DNA to allow for replication as well as the transcription of our DNA. A DNA helicase is an enzyme that functions by melting the hydrogen bonds that hold the DNA into the double helix structure. It is also known as 'Unwindase'. So, the correct option is 'unwindase/Helicase'.
