Report Abuse. Transcription does require a helicase. In eukaryotes, TFiiH (one of the general transcription factors of the transcription pre-initiation complex) has helicase activity and aids in the formation of the transcription bubble. Erin Â· 2 years ago.
The mechanism of transcription has parallels in that of DNA replication. As with DNA replication, partial unwinding of the double helix must occur before transcription can take place, and it is the RNA polymerase enzymes that catalyze this process.ranscription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
