摘要：

Bacterial genes providing for single metabolic functions are found in operons, possibly because this organization allows efficient horizontal transfer among organisms. Transferred genes can confer novel metabolic phenotypes on their new hosts and allow rapid, effective exploitation of new environmental niches. Moreover, the mobility of selfish operons may facilitate bacterial speciation.
