Found in Eukaryotic cells, RNA polymerase II is used to transcribe all protein-encoding genes, and in addition, many of the small nucleolar RNAs (snoRNA) and the majority of the micro RNAs (miRNA)[1]. RNA polymerase II cannot transcribe DNA on its own: the many elements that make up the pre-initiation complex (PIC) must assemble at the site of the promoter in order for RNA polymerase II to be recruited and begin transcription[2]. The PIC is made up of Transcription Factors: TFIID, TFIIA, TFIIB, TFIIF, TFIIE, TFIIH[3].
