Satellite (unranked): (unranked): Satellite Groups Satellite viruses Satellite nucleic acids A satellite is a composed of that depends on the of a host cell with a for its replication.
Satellite viruses, which are most commonly associated with plants, but are also found in mammals, arthropods, and bacteria, have the components to make their own protein shell to enclose their genetic material, but rely on a to replicate. Most viruses have the capability to use host enzymes or their own replication machinery to independently replicate their own viral RNA. Satellite viruses in contrast, are completely dependent on a for replication. The symbiotic relationship between a satellite and a helper virus to catalyze the replication of a satellite viral genome is also dependent on the host to provide components like to carry out replication. A satellite virus of that inhibits the replication of its host has been termed a.
However, the usage of this term remains controversial due to the lack of fundamental differences between virophages and classical satellite viruses. The genomes of satellite viruses range upward from 359 nucleotides in length for Satellite Tobacco Ringspot Virus RNA (STobRV). Satellite viral particles should not be confused with.
