WebRNA polymerases are large, multi-subunit complexes. They contact 70–90 base pairs of DNA in promoter regions used to initiate DNA transcription, during which DNA wraps around the polymerase. Eukaryotes have three different types of RNA polymerases: • RNA polymerase I (Pol I), used to produce the large ribosomal subunit;. RNA polymerase II … WebPurification of multisubunit protein complexes such as human TFIIH and RNA polymerase II has been a tedious task by conventional chromatography. To overcome the difficulty in isolating human TFIIH and RNA polymerase II, which play an essential role in eukaryotic transcription, we have developed an effective purification scheme that allows TFIIH and …
