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 ...

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

When DNAse and RNAse (enzymes that degrade DNA and RNA ... the polymerase. Cleavage seems to be coupled with termination of transcription and occurs at a consensus sequence. Mature pol II mRNAs ...
