• (A) RNA polymerase I (RNA Pol I) is located in the nucleolus and transcribes the 28S, 18S, 5.8S rRNA genes
• (B) RNA polymerase II (RNA Pol II) is located in the nucleoplasm and transcribes protein coding genes to yield pre-mRNA and also the genes encoding small nuclear RNAs (snRNA) involved in RNA processing
• (C) RNA polymerase III (RNA Pol III) is located in the nucleoplasm and transcribes genes for tRNA, 5S rRNA, and the 7S rRNA
• (D) All of the above
