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 ...

Three different types of RNA polymerase exist in eukaryotic cells ... Enhancer sequences do what their name suggests: They act to enhance the rate at which genes are transcribed, and their ...

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 ...
