Marnavirus
Encyclopedia
Marnavirus is the only known genus within the family Marnaviridae. Virions consist of a round, non-enveloped capsid
with icosahedral symmetry. The capsid is isometric
.
The genome
is a non-segmented single molecule of positive-sense, single-stranded RNA
of about 9000 nucleotides in length.
Capsid
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic...

Isometric
The term isometric comes from the Greek for "having equal measurement".isometric may mean:* Isometric projection , a method for the visual representation of three-dimensional objects in two dimensions; a form of orthographic projection, or more specifically, an axonometric projection.* Isometry and...

The genome
Genome
In modern molecular biology and genetics, the genome is the entirety of an organism's hereditary information. It is encoded either in DNA or, for many types of virus, in RNA. The genome includes both the genes and the non-coding sequences of the DNA/RNA....
