Definition

noun

Any of the viruses belonging to the Class II of Baltimore classification system characterized by having a single stranded DNA as the genetic material and using a DNA-dependent DNA polymerase during replication.


Supplement

Most of these viruses must enter the host nucleus before they can replicate. It is because they use the host cell's polymerases when replicating their viral genome. The parvoviruses are example of this group.

Variant: ssDNA virus.

Compare: double stranded DNA virus.
