Answer :
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.
Also known as DNA dependent RNA plymerase, its primary role is to produce primary transcript RNA, by using DNA as a template. The process is called as transcription. RNA polymerase is present in almost all of the organsims, but may be present in different numbers in each organsim.
