|Genome: DNA Virus, dsDNA Virus||Structure: Enveloped Virus|
- Poxviruses are a family of related viruses characterized by their extremely large physical size, complex genome, and capacity to replicate in the cytoplasm of host cells. Poxviruses are large enough to be seen by light microscopy and appear as brick-shaped particles. Their dsDNA viral genome is large, complex, and codes for it own RNA and DNA polymerase, allowing pox viruses to replicate within the host cell cytoplasm rather than depend on factors within the host nucleus. In general, pox viruses tend to produce lesions of the skin.
