Also have segmented or any Gino which allows it to change its antigens where is para have a nonsegmented or any Ginos

ortho is smaller and doesnt have giant cell formaton

para have f spikes Enabling cell to cell fusion and that forms multinucleate giant cells

Paramyxoviridae also replicate in the upper respiratory tract and can produce influenza-like illness, but
they also produce a PARAde of distinctly different diseases. The paramyxoviridae include parainfluenza

Q

poxivirdae and what does it cause

A
dna virus 
breaks the rule as replicates in the cytoplasm
very complex
like herpes it has an evelope 
does not have an isocohedral shape

causes chicekn pox (variola)

Viruses acquire this
membrane by budding through the host cell nuclear or
