RNA polymerase II synthesizes precursors of mRNAs and most sRNA and microRNAs.
WebThe Three Eukaryotic RNA Polymerases. The features of eukaryotic mRNA synthesis are markedly more complex than those of prokaryotes. Instead of a single polymerase comprising five subunits, the eukaryotes have three polymerases that are each made up of 10 subunits or more.
