Answer:
Initiation Transcription or (promoter)
Explanation:
∙ Transcription is the process of RNA production from DNA.
∙ During transcription, RNA polymerase produces a copy of a gene from the DNA to mRNA.
∙ During transcription, the DNA location at which RNA polymerase interacts is termed a promoter.
∙ Transcription begins with attachment of sigma factor proteins to the RNA polymerase holoenzyme, therefore, allowing it to bind to promoter DNA.
∙ RNA polymerase forms a transcription bubble, which divides the two strands of the DNA helix.
∙ Then RNA polymerase proceeds towards the transcription start site for the process of transcription.
