What is the role of general transcription factors?
GTFs bind to enhancers or silencers and regulate transcription
GTFs bind to the core promoter and allow transcriptional initiation
GTFs are cis-acting regulatory sequences
GTFs regulate the length of the mRNA
GTFs are part of the RNA polymerase II holoenzyme, and control transcription initiation
