WebAbstract. Polyadenylation [poly (A)] signals (PAS) are a defining feature of eukaryotic protein-coding genes. The central sequence motif AAUAAA was identified in the mid-1970s and subsequently shown to require flanking, auxiliary elements for both 3′-end cleavage and polyadenylation of premessenger RNA (pre-mRNA) as well as to promote ... WebPre-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. Errors in splicing are implicated in cancers ...

The precursor mRNA or pre-mRNA is the primary transcript in the transcription process. It has both exons (coding sequence) and introns (non-coding sequence).
