WebFigure 15.14 Pre-mRNA splicing involves the precise removal of introns from the primary RNA transcript. The splicing process is catalyzed by protein complexes called spliceosomes that are composed of proteins and RNA molecules called snRNAs. Spliceosomes recognize sequences at the 5' and 3' end of the intron. WebJul 19, 2024 · RNA involvement in self‑splicing is stoichiometric, but the excised intron does have a catalytic activity in vitro. After a series of intramolecular cyclization and cleavage …

WebInfo. In most eukaryotic genes, coding regions (exons) are interrupted by noncoding regions (introns). During transcription, the entire gene is copied into a pre-mRNA, which includes exons and introns. During the process of RNA splicing, introns are removed and exons joined to form a contiguous coding sequence. WebTransfer RNA (tRNA) introns have been detected in all three kingdoms of life, and their precise removal is crucial for tRNA function. Of particular interest to this review are the tRNA intronic circular RNAs (tricRNAs) that form during metazoan tRNA splicing. In animal cells, these ultrastable introns form a novel class of noncoding RNA. WebMar 30, 2024 · RNA editing calls in GM12878.
