Agent 81. Satellites


Definition

Satellites are sub-viral agents composed of nucleic acid molecules that depend for their productive multiplication on co-infection of a host cell with a helper virus. Satellite nucleic acids have substantially distinct nucleotide sequences from those of the genomes of either their helper virus or host. When a satellite encodes the coat protein in which its nucleic acid is encapsidated it is referred to as a satellite virus.
