It usually occurs in bacteria, sometimes in eukaryotic organisms.Some plasmids can become associated with another plasmid or with nuclear chromosome; in the latter case, the plasmid is known as episome. In another words, an episome is a plasmid of bacteria or viral DNA that can integrate itself into the chromosomal DNA of the host organism.F
