False-colour transmission electron micrograph of virus particles of the papilloma virus,or wart virus,which belongs to the papovavirus class. Papilloma viruses cause warts to grow on the hands & feet as well as on the mucous membranes in the mouth,& on the genitals. Individual virions have icosahedral capsid symmetry (35-45 nanometres across) & do not possess a lipoprotein envelope. Genetic information is in the form of double- stranded DNA contained within the protein capsid. Nearly all members of the group are oncogenic or capable of producing tumours.
