Structure

Viruses in Cryspovirus are non-enveloped, with icosahedral geometries, and T=1 symmetry. The diameter is around 30-35 nm. Genomes are linear and segmented, around 2.1kb in length. The genome codes for 2 proteins.^[1]

Genus	Structure	Symmetry	Capsid	Genomic Arrangement	Genomic Segmentation
Cryspovirus	Icosahedral	T=1	Non-Enveloped	Linear	Segmented

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Protists serve as the natural host.^[1]
