Transcriptional termination by RNA polymerase II in yeast occurs by two different pathways: stable or cryptic unstable transcripts use the Nrd1 complex, whereas mRNA uses 3' cleavage and polyadenylation factors together with Rat1 exonuclease. How RNA polymerase II selects which pathway to use is discussed.
