Rolling-Circle ReplicationReplication by the RC mechanism has to be unidirectional, and it is considered to be an asymmetric process because synthesis of the leading strand and synthesis of the lagging strand are uncoupled (reviewed in references 69, 84, 108, 150, 150a, and 228). One of the most relevant features of RC replication is that the newly synthesized leading plus strand remains coval..

Plasmids are extrachromosomal DNA elements with characteristic copy numbers within the host. These replicons have been found in species from the three representatives of the living world, namely, the domains Archaea, Bacteria, and Eukarya (318). Plasmids may constitute a substantial amount of the total genetic content of an organism, representing more than 25% of the genetic material of the cell..
