A cartoon depiction of a lentiviral genome forming an episome in the presence of non-functional LV integrase. The linear lentiviral genome has a long terminal repeat (LTR) on each end. A split arrow shows two paths for circular episome formation. Homologous recombination within the LTRs results in a single LTR in the circular episome. Non-homologous end joining results in two adjacent LTRs in the circular episome.
