Transcription of Genes: Are Specific Transcription Factors + Enhancers Necessary? I learned about transcription in my AP Biology class and we discussed how transcription occurs, but I was wondering whether transcription always requires the enhancers, activators (specific transcription factors), DNA-bending proteins, etc. to be present, or if this is only used for higher-level production of RNA transcripts? Can transcription occur if only the RNA Polymerase (I, II, or III) and the General Transcription Factors are present? Thanks!

enhancers, activators, silencers, repressors are necessary in controlling of the transcriptional process. Utilization of enhancers/silencers plays a part in differentiation of developmental processes (i.e. maturation, growth)
