WebJun 18, 2024 · Plasmid incompatibility or the inability of two plasmids to reside in the same cell has been another way to classify plasmids. Plasmids belonging to the same incompatibility group have identical or very similar replication and/or segregation gene modules ( Novick, 1987 ; Austin and Nordström, 1990 ). WebInitial schemes were based on the ability of a plasmid to inhibit F fertility, but due to certain limitations, these methods were superseded by incompatibility or Inc typing. Inc typing classifies plasmids by their ability to stably coexist with other plasmids in the same bacterial strain, a trait that is dependent on their replication machinery.
