Punavirus
Punavirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts. There are currently four species in this genus, including the type species Escherichia virus P1.[1][2]

Structure
Viruses in Punavirus are non-enveloped, with icosahedral and head-tail geometries. The diameter is around 85 nm. Genomes are circular, around 100kb in length. The genome codes for 100 proteins.[1]

| Punavirus | Head-Tail | Non-enveloped | Circular | Monopartite |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
