Virion Properties
Nucleic acid is not encapsidated and virus relies for
encapsidation on a helper virus.
Nucleic Acid
The genome is monopartite, only one particle size is
recovered of linear, negative-sense and positive-sense,
single-stranded, or double-stranded DNA. The complete genome is
4700 nucleotides long, is sequenced and complete sequence is
about 4700 nucleotides long. The genome has terminally redundant
sequences. The terminally redundant sequences have of 145
nucleotides has inverted terminal repetitions with a palindromic
sequence (or the first 125).
Genome Organization and Replication
By itself, genomic nucleic acid is infectious (under
permissive conditions.

Genome Organization and Replication
By itself, genomic nucleic acid is infectious (under
permissive conditions. Under non-permissive conditions the
dependovirus genome integrates in the host genome to establish a
latent infection).
Translation: Virions are
associated with helper virus and dependent on co-infection of
helper virus during replication, or are associated with helper
virus, but independent from its functions during replication
(under permissive conditions in cultured cells. Helper viruses
are adenovirus or herpesvirus which render the intracellular
environment permissive for replication).
