| Abstract | Accessory DNA elements whether they be virus, plasmids or transposable elements have in common the ability to over-replicate the DNA, with respect to their hosts. The sophisticated bio-chemical and regulatory mechanisms of many accessory elements suggest that they are the products of long term selection. Bacterial euchromosomal genes are generally co-adapted complexes, so any genetic inter change is mostly deleterious. Accessory genes on the other hand are transferable among the different strains or species of bacteria and are selected to function successfully in all of them. Accessory DNA could serve as mapping zones of biodiversity and could reflect on the nature of survival and adaptation of bacteria in an ever changing environment. |
