5 - The F-plasmid, a paradigm for bacterial conjugation

WitrynaPlasmids used by scientists today come in many sizes and vary broadly in their functionality. In their simplest form, plasmids require a bacterial origin of replication (ori), an antibiotic-resistance gene, and at least one unique restriction enzyme recognition site. These elements allow for the propagation of the plasmid within bacteria, while ... WitrynapSC101 Low copy number plasmid from Salmonella. pSC101 was the first plasmid vector used for cloning.
