Virus Shapes
Polyhedral
Polyhedral viruses have many triangular sides. Examples of polyhedral viruses: HPV, Adenoviruses (cold), polio, Hep A
Spherical
example of spherical virus: influenza
Structure of spherical virus may be studded with receptors, may be enveloped
Helical
example of helical virus: TMV
What nucleic acid does a helical virus contain: either DNA or RNA
Complex
Complex viruses: no identifiable capsids but several layers of COATS around NA.
Examples of complex virus: Bacteriophage, poxviruses
