Extrachromosomal DNA in eucaryotes.
Eucaryotic extrachromosomal DNAs have been organized into four major classes: (1) Organelle DNAs, (2) plasmid DNAs, (3) amplified genes, and (4) intermediates and/or by-products of DNA transpositions and rearrangements. In this review some of the relatively well-characterized members of each class are described; it is suggested that many of them reflect the complexity and plasticity of eucaryotic genomes.
