S uc u e and Mo phology o Vi uses
Vi uses consis o nucleic acid (DNA o RNA) and a p o ein coa — he capsid —
which p o ec s he gene ic ma e ial. Some i uses possess an addi ional lipop o ein

Acco ding o he shape o he capsid, i uses a e classi ied as helical, icosahed al,
complex, o sphe ical. The size o i al pa icles anges om 20 o 300
nanome e s, making hem isible only unde an elec on mic oscope.
