Viruses

these are our viruses

polyhedral

Have many triangular sides

HPV, Adenoviruses (cold), polio, Hep A

spherical

Structural determinations of spherical viruses have so far been limited to the capsid shell with icosahedral symmetry.

complex

A special type of icosahedral shape, called a prolate, is a variant of the icosahedral viral shape and is found in bacteriophages

helical

long rigid/flexible rods consisting of capsomeres arranged helically around NA (form hollow capsid tube)
