Satellite nucleic acids consist of those satellites that do not encode their own coat protein (unlike satellite viruses) but are encapsidated in that of the helper virus. Particles containing satellite nucleic acid are therefore antigenically identical to those of the helper virus but can sometimes be distinguished by physical features such as sedimentation rates.
Single stranded satellite RNAs are all associated with plant viruses and several subgroups are recognised on the basis of their replication strategies.
|Large satellite RNAs||(0.8-1.5 kb, encoding a non-structural protein)|
|Small linear satellite RNAs||(less than about 0.9 kb, encoding no functional protein; always linear)|
|Circular satellite RNAs||(c. 350 nucleotides, encoding no functional protein; some circular molecules present)|
