Title: Re: Outline the basic differences in function among RNA polymerases in both prokaryo Post by: duddy on Jul 11, 2012 Only one type of RNA polymerase is found in prokaryotes, so all classes of genes are transcribed by it. Eukaryotes have three distinct RNA polymerases, each of which transcribes different gene types. RNA polymerase I transcribes the genes for the 28S, 18S, and 5.8S ribosomal RNAs; RNA polymerase II transcribes mRNA genes and some snRNA genes; and RNA polymerase III transcribes genes for the 5S rRNAs, the tRNAs, and the other snRNAs.
