obsolete pre-mRNA cleavage required for polyadenylation (obsolete GO:0098789)
OBSOLETE. The targeted, endonucleolytic cleavage of a pre-mRNA, required for polyadenylation of the 3' end. This cleavage is directed by binding sites near the 3' end of the mRNA and leaves a 3' hydoxyl end which then becomes a target for adenylation.
