WebApr 1, 2002 · Introduction. The genes of complex eukaryotes are interrupted by introns. Explanations for the origins of these introns are that either they were added (Logsdon Jr. 1998), as adventitious elements or by splicing between gene duplications (Venkatesh, Ning, and Brenner 1999), to previously continuous genes or they arose because the gene in … WebIntrons are nothing more than genetic load in the eukaryotic genome.
