Entomobirnavirus

Entomobirnavirus is a genus of viruses, in the family Birnaviridae.[1] The fly Drosophila melanogaster is the natural host. There are currently only two species in this genus, including the type species Drosophila X virus.[2][3]

Structure

Viruses in the genus Entomobirnavirus are non-enveloped, with icosahedral and Single-shelled geometries, and T=13 symmetry. The diameter is around 70 nm. Genomes are linear and segmented, around 15.3.2-3.5kb in length. The genome codes for 5 proteins.[2][3]

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. Drosophila melanogaster serve as the natural host.[2][3]

gollark: WHO CARES?! and also no, Rust may be better sometimes.
gollark: As in, literally impossible to unambiguously parse without executing previous bits of code.
gollark: Also, are almost certainly unparseable, like Perl.
gollark: But sentences can also contain clauses.
