Reference no: EM13113845

You have identified a mutation in yeast, a unicellular eukaryote, that prevents the polyadenylation of the 3' end of RNA transcripts. However, there is no mutation in the enzyme that catalyzes the addition of A's or in the enzyme that cleaves the nascent RNA after transcription is complete. Which molecule may have been mutated?
