Any process involved in forming the mature 3' end of a non-coding RNA molecule. The enzymatic addition of a sequence of adenylyl residues at the 3' end of a non-coding RNA (ncRNA) molecule. In eukaryotes, substrates include nuclear non-coding RNAs such as precursors and a variety of incorrectly processed forms of snRNAs, snoRNAs, rRNAs, and tRNAs, as well as discarded RNA fragments which have been removed from ncRNA primary transcripts. Polyadenylation of precursors is often linked to termination of transcription, but polyadenylation of RNAs targeted for degradation may also occur post-transcriptionally. This polyadenylation is important both for 3'-end processing to produce mature ncRNA species and also for targeting incorrectly processed or discarded RNA molecules for degradation. Any process that results in the conversion of one or more primary non-coding RNA (ncRNA) transcripts into one or more mature ncRNA molecules. The enzymatic addition of a sequence of adenylyl residues (polyadenylation) at the 3' end of a non-coding RNA, occurring as part of the process of polyadenylation-dependent non-coding RNA catabolism. The enzymatic addition of a sequence of adenylyl residues at the 3' end of an RNA molecule. Any process involved in forming the mature 3' end of an RNA molecule. The enzymatic addition of a sequence of adenylyl residues at the 3' end of snoRNA molecule. In eukaryotes, this occurs in conjunction with termination of transcription of precursor snoRNA molecules and may occur post-transcriptionally on incorrectly processed molecules targeted for degradation.
