Structure

Viruses in ''Tevenvirinae'' are non-enveloped, with head-tail geometries. These viruses are about 70 nm wide and 140 nm long. Genomes are linear, around 170-245kb in length. The genome codes for 300 to 415 proteins.

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. The virus exits the host cell by lysis, and holin/endolysin/spanin proteins. Bacteria and archaea serve as the natural host. Transmission routes are passive diffusion.
