TY - JOUR AU - Martin, Fergal J. AU - McInerney, James O. PY - 2009 DA - 2009/02/10 TI - Recurring cluster and operon assembly for Phenylacetate degradation genes JO - BMC Evolutionary Biology SP - 36 VL - 9 IS - 1 AB - A large number of theories have been advanced to explain why genes involved in the same biochemical processes are often co-located in genomes. Most of these theories have been dismissed because empirical data do not match the expectations of the models. In this work we test the hypothesis that cluster formation is most likely due to a selective pressure to gradually co-localise protein products and that operon formation is not an inevitable conclusion of the process.
