The process in which transcription of nonpolyadenylated RNA polymerase II transcripts is terminated; coupled to the maturation of the RNA 3'-end.

Any process involved in forming the mature 3' end of an mRNA molecule.

Any process involved in forming the mature 3' end of a snoRNA molecule.

Any process involved in forming the mature 3' end of an snRNA molecule.

The process in which the 3' end of a pre-tRNA molecule is converted to that of a mature tRNA.

The set of processes involved in identifying and degrading defective or aberrant mRNAs within the nucleus.

The chemical reactions and pathways resulting in the breakdown of cryptic unstable transcripts (CUTs).

The chemical reactions and pathways resulting in the breakdown of antisense transcripts, i.e. transcripts that were produced from the antisense strand of a gene that produces a gene product and which often have a regulatory effect on the transcription of that gene product.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A complex that functions in transcription termination of RNA polymerase II transcribed non-coding RNAs. This complex interacts with the carboxy-terminal domain (CTD) of PolII and the terminator sequences in the nascent RNA transcript. In yeast this complex consists of Nrd1p, Nab3p, and Sen1p.
