<span> RNA polymerase is commonly know as DNA-dependent RNA polymerase. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. It is found in the core of eukaryotic cells. One of which combined rRNA in the nucleolus while the rest of the chemical blends other RNA in the nucleoplasm, some portion of the core yet outside the nucleolus.</span>
