In a typical cloning experiment, a target gene is inserted into a circular piece of DNA called a plasmid. The plasmid is introduced into bacteria via a process called transformation, and bacteria carrying the plasmid are selected ... Plasmid replication processes are host-specific and influence plasmid copy number. In the 4 kilobase region of the DNA fragment, plasmid replicons contain one or more origins of replication (ori) and a small number of regulatory components, such as Rep proteins. Moreover, plasmids contain a few important genes that aid in DNA replication.Naturally occurring viruses harbor genetic material (termed the viral genome) that, in general, encodes for more viruses.
