RNA Polymerases are enzymes involved in the production of RNA. After the annealing of a primer, RNA polymerases build a complementary strand of RNA from free nucleotides using a strand of DNA as a template. The active form is a complex consisting of multiple subunits known as the RNA polymerase holoenzyme (Molecular mass ~400 kilodaltons) [1].
In Eukaryotes some RNA polymerases include:
- RNA_polymerase_I: Involved in the transcription of ribosomal RNA.
- RNA_polymerase_II: Transcribes all genes that code for proteins.
- RNA_polymerase_III: Involved in the transcription of transfer RNA (tRNA)
