| Might there be a universal selective benefit that could explain the evolutionary persistence of introns? |
| These observations corroborate results of the cognate introns in the myxomycetes Didymium and Physarum, where no in vitro splicing products were detected. |
| The open reading frames of all gene sequences identified were interrupted by introns. |
| He concluded that recombination had separated the genealogical histories of introns and exons within these genes. |
| The differences between plants and animals may be especially pronounced with regard to introns. |
| Sequence data for each gene encompassed all coding exons and the intervening introns. |
