The chemical reactions and pathways involving snoRNA, small nucleolar RNA, any of a class of small RNAs that are associated with the eukaryotic nucleus as components of small nucleolar ribonucleoproteins. They participate in the processing or modifications of many RNAs, mostly ribosomal RNAs (rRNAs) though snoRNAs are also known to target other classes of RNA, including spliceosomal RNAs, tRNAs, and mRNAs via a stretch of sequence that is complementary to a sequence in the targeted RNA. The chemical reactions and pathways involving 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. Transfer RNA is characterized by the presence of many unusual minor bases, the function of which has not been completely established. The chemical reactions and pathways involving rRNA, ribosomal RNA, a structural constituent of ribosomes. The chemical reactions and pathways involving snRNA, small nuclear RNA, any of various low-molecular-mass RNA molecules found in the eukaryotic nucleus as components of the small nuclear ribonucleoprotein. 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. Any cellular metabolic process involving nucleic acids. The chemical reactions and pathways involving macromolecules, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass, as carried out by individual cells. 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 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. The chemical reactions and pathways involving non-coding RNA transcripts (ncRNAs). The chemical reactions and pathways involving 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 involving cryptic unstable transcripts (CUTs), which are transcribed from intergenic regions. Many intergenic regions are heavily transcribed, but the transcripts are rarely detected due to rapid degradation by the nuclear exosome. The chemical reactions and pathways involving 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 involving antisense RNA, an RNA molecule complementary in sequence to another RNA or DNA molecule, which, by binding the latter, acts to inhibit its function and/or completion of synthesis.
