Introns are almost always present in ribosomal protein genes, even in organisms in which introns are rare. Although trans spliced, the trypanosome ribosomal protein gene S14 apparently does not have cis introns, which supports the notion that such introns are absent in this organism.
内含子几乎总是存在于核糖体蛋白基因中,即使在那些内含子很少见的生物体内也是如此。尽管锥虫的核糖体蛋白基因S14存在反式剪接,但显然没有顺式内含子,这支持了该生物体内不存在此类内含子的观点。
