Abstract

Many pairs of genes whose gene products are functionally related lie either 90 degrees or 180 degrees apart on the circular map of the E. coli chromosome. A mechanism of evolution is proposed that involves two sequential duplications of an ancestral genome, followed by mutation and divergence of function of replicate genes.
