Plasmid

..., seven different plasmids have been found in E. coli . On the other hand, related plasmids are often 'incompatible', resulting in the loss of one of them from the cell line. Therefore, plasmids can be assigned into incompatibility groups , depending on their ability to coexist in a single cell. These...
