The chemical reactions and pathways resulting in the breakdown of a macromolecule, any large molecule including proteins, nucleic acids and carbohydrates, as carried out by individual cells. The chemical reactions and pathways resulting in the breakdown of rRNA, ribosomal RNA, a structural constituent of ribosomes. The cellular chemical reactions and pathways involving RNA, ribonucleic acid, one of the two main type of nucleic acid, consisting of a long, unbranched macromolecule formed from ribonucleotides joined in 3',5'-phosphodiester linkage. The set of processes involved in identifying and degrading defective or aberrant ncRNAs within the nucleus. The chemical reactions and pathways resulting in the breakdown of non-coding RNA transcripts (ncRNAs). Includes the breakdown of cryptic unstable transcripts (CUTs). The chemical reactions and pathways involving non-coding RNA transcripts (ncRNAs). The chemical reactions and pathways resulting in the breakdown of cryptic unstable transcripts (CUTs). The chemical reactions and pathways resulting in the breakdown of tRNA, transfer RNA, a class of relatively small RNA molecules responsible for mediating the insertion of amino acids into the sequence of nascent polypeptide chains during protein synthesis. The chemical reactions and pathways resulting in the breakdown of snRNA, small nuclear RNA, low-molecular-mass RNA molecules found in the eukaryotic nucleus as components of the small nuclear ribonucleoprotein. The chemical reactions and pathways resulting in the breakdown of miRNA, microRNA, a class of single-stranded RNA molecules of about 21-23 nucleotides in length, which regulates gene expression. The chemical reactions and pathways resulting in the breakdown of snoRNA, small nucleolar RNA, any of a class of small RNAs that are associated with the eukaryotic nucleus as components of small nucleolar ribonucleoproteins. The chemical reactions and pathways resulting in the breakdown of RNA, ribonucleic acid, one of the two main type of nucleic acid, consisting of a long, unbranched macromolecule formed from ribonucleotides joined in 3',5'-phosphodiester linkage. 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. The chemical reactions and pathways resulting in the breakdown of piRNAs, Piwi-associated RNAs, a class of 24- to 30-nucleotide RNA derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism. The chemical reactions and pathways resulting in the breakdown of 21U-RNAs, a class of single-stranded RNA molecules of about 21 nucleotides in length characterized by a uridine 5'-monophosphate and a modified 3' end resistant to periodate degradation. 21U-RNAs are derived from distinct, autonomously expressed loci within the genome.
