Step-by-step solution

In eukaryotes, there are three types of RNA polymerases: RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S). RNA polymerase II transcribes the precursor of mRNA, the heterogeneous nuclear RNA (hnRNA). RNA polymerase III transcribes tRNA, 5S rRNA, and snRNAs. Initiation of transcription in prokaryotes is facilitated by the binding of the sigma ( ) factor to the RNA polymerase enzyme, which helps it recognize the promoter site. Tailing is a post-transcriptional modification in eukaryotes where a poly-A tail (abo
