Viruses or virions are very small infectious particles composed of dna or rna enclosed within a protein coat or capsid.

Anatomy of a virus. In general the shapes of viruses are classified into four groups. A virus structure can be one of the following. Viruses come in many shapes and sizes but these are consistent and distinct for each viral family.

Essentially an icosahedral shape is formed by the fusion of many equilateral triangles. Icosahedral enveloped complex or helical. Viruses can infect all types of life forms from animals and plants to microorganisms including bacteria and archaea.

A virus is a small infectious agent that replicates only inside the living cells of an organism. Viruses with the helical structure are composed of capsomeres that are identical. When a single virus is in its complete form and has reached full infectivity outside of the cell it is known as a virion.

Filamentous viruses are long and cylindrical. Viral structure types helical. Viral genome is protected by a protein capsid.

Filamentous isometric or icosahedral enveloped and head and tail. These viruses appear spherical in shape but a closer look actually reveals they are icosahedral. The genome may be circular or straight.
