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 ...

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 ...

In Eukarya, RNA Polymerase II (Pol II) transcription is a highly regulated process ... either through a stepwise assembly of other basal transcription factors or through recruitment of a pre-assembled ...
