Plazmid – cząsteczka pozachromosomowego DNA występująca w cytoplazmie komórki, zdolna do autonomicznej replikacji. Termin „plazmid” został po raz pierwszy zaproponowany przez Joshuę Lederberga w 1952 roku, jako genetyczna nazwa wszystkich znanych (w tamtym czasie) „pozachromosomowych cząstek genetycznych”, a w praktyce zaczął funkcjon…
