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 ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

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 ...
