abstract：:New transcripts generated by RNA polymerase II (RNAPII) are generally processed in order to form mature mRNAs. Two key processing steps include a precise cleavage within the 3' end of the pre-mRNA, and the subsequent polymerization of adenosines to produce the poly(A) tail. In yeast, these two functions are performed ...
