WebApr 30, 2002 · Nuclear introns have specific short terminal sequences required for proper excision, almost always bearing a GT at the 5′ end and an AG at the 3′ end. In animals, most introns have a polypyrimidine tract of >10 nucleotides before the canonical AG, and an interior branch-point A is essential for the splicing reaction. WebMar 7, 2011 · In bacterial, bacteriophage, archaeal, eukaryotic, and organelle genomes, RNAs of very different function (tRNAs, rRNAs, and mRNAs) often contain introns.
