Summary

A model is presented whereby the formation of gene clusters in bacteria is mediated by transfer of DNA within and among taxa, and predicts a mosaic structure of modern genomes in which ancestral chromosomal material is interspersed with novel, horizontally transferred operons providing peripheral metabolic functions.
