Virophages and satellite virus’ lifestyle. (A) The replication of virophages is supposed to occur entirely in the virus factory of its giant virus host, depending of the giant virus expression/replication complex. (B) The concept of satellite virus implicates that the virus initiates the expression and replication of its genome in the nucleus using the host cell machinery and then goes to the cytoplasm. In the cytoplasm, the satellite virus hijacks the morphogenesis machinery of its helper virus to produce its progeny.
