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 ...

There are a variety of different types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is responsible for creating messenger RNA (mRNA), which is the main ...

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 ...
