Witryna8 paź 2014 · The origins of replication ( ori) are plasmid-borne DNA sequences that direct the host cell to initiate plasmid replication and are thus essential for plasmid propagation. This is accomplished by various proteins (initiators and repressors) binding to the sequence that make up the ori. 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…
