摘要: Accumulating evidence that introns are highly restricted in their phylogenetic distribution strongly supports the view were inserted late eukaryotic evolution into preformed genes and, hence, exon-shuffling played no role assembly of primordial genes. Potential mechanisms intron insertion and possible nuclear splicing machinery from self-splicing group II also discussed.
