cytoplasmic polyadenylation-dependent rRNA catabolic process
cytoplasmic polyadenylation-dependent rrna catabolic process
The chemical reactions and pathways occurring in the cytoplasm and resulting in the breakdown of a ribosomal RNA (rRNA) molecule, initiated by the enzymatic addition of a sequence of adenylyl residues (polyadenylation) at the 3' end the target rRNA truncated degradation intermediate.
