What Are The Components Of The Transcription Initiation Complex?
What Are The Components Of The Transcription Initiation Complex? A transcription-initiation complex comprises an RNA polymerase and various general transcription factors bound to the promoter region. What protein components are needed for transcription initiation? Transcription of eukaryotic nuclear genes requires three different RNA polymerases: RNA polymerase I, RNA polymerase II and RNA polymerase III. Each
