13 FULL TEST BANK ACCURATE QUESTIONS
AND CORRECT ANSWERS 100% PASS
◉virion . Answer: the complete infective form of a virus outside a host
cell, with a core of RNA or DNA and a capsid
◉host range . Answer: the spectrum of host cells a virus can infect
◉bacteriophages . Answer: viruses that infect bacteria
◉nucleic acid . Answer: DNA or RNA can be single or double stranded,
and either linear or circular
◉capsid . Answer: protein coat made of capsomeres (subunits)
◉envelope . Answer: lipid, protein, and carbohydrate coating on some
viruses
◉spikes . Answer: projections from outer surface
, ◉enveloped virus . Answer: viruses whose capsids are covered by an
envelope. usually consist of lipids, proteins, and carbohydrates
◉non- enveloped virus . Answer: viruses whose capsids aren't covered
by an envelope
◉helical viruses . Answer: are hollow cylinders surrounding the nucleic
acid
◉polyhedral viruses . Answer: are many sided
◉complex viruses . Answer: Have complex structures
Ex. Many bacteriophages have a Polyhedral capsid with a helical tail
attached.
◉plaque method . Answer: for detecting and counting viruses on solid
media
◉plaques . Answer: clearings in a bacterial lawn resulting from lysis of
phages
◉plaque forming units . Answer: the concentration of viral suspension
by the number of plaques
