Eukaryotes transcribe much of their genomes, but little is known about the fidelity of transcriptional initiation by RNA polymerase II in vivo.I suggest that ∼ 90% of Pol II initiation events in ...

The Pre-Initiation Complex (PIC), which consists of Mediator, TFIIA, TFIIB, TFIID, TFIIE, TFIIF, TFIIH, and RNA polymerase II (pol II), governs the expression of all protein-coding and most non-coding ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase ... I transcribes ribosomal RNAs (rRNAs), RNA pol II transcribes RNAs that will become messenger RNAs ...
