rna polymerase location
In the nucleus of eukaryotes, transcription is carried out by three different RNA polymerases, RNA polymerase I, II and III (Pol I, II and III) (1). Each of them is dedicated to the transcription of distinct sets of genes, but none is able to recognize its target promoters independently.n the nucleus of eukaryotes, transcription is carried out by three different RNA polymerases, RNA polymerase I, II and III (Pol I, II and III) (1).
