Notes on Genus: Small linear satellite RNAs
no particles of their own
This is one of three groups of ss satellite RNAs
. Like the other groups, the RNA is encapsidated within the coat protein of its helper virus. Members are distinguished by having genomes of less than about 900 nucleotides which do not encode any functional protein and which are never present as circular molecules. The satellites can substantially modify the symptoms of helper virus infection.
There are no distinctive virions, because the satellite RNA is encapsidated by the helper virus.
Monopartite, single-stranded, RNA of less than about 900 nucleotides.
