WebbHow does plasmid replication occur? Most plasmids of gram-positive bacteria replicate by a rolling circle mechanism similar to that used by phage φx174. Most linear plasmids replicate by means of a mechanism that involves a protein bound to the 5′-end of each DNA strand that is used in priming DNA synthesis. Webbc. On the schematic at the top.
