WebPlasmids possess mechanisms that ensure their independent replication as well as those that regulate their replication number and guarantee stable inheritance during cell division. By the conjugation process, they can stimulate lateral transfer between bacteria from various genera and kingdoms. [2] WebJun 19, 2024 · Bacteria containing plasmid are termed F positive (F+), and those without plasmids are F negative (F–). Two F+ bacteria result upon conjugation of an F+ bacterium with an F– bacterium. Each bacterium is only able to contain one F-plasmid . Figure 1.
