DETAILED ANSWERS WITH
RATIONALES
, True or False. Because the genome is contained within an enclosed space (much like
the nucleus of a cell), viruses are classified as eukaryotic. - ANSWERFalse
True or False. Although viruses may contain their genome within an enclosed space
(much like the nucleus of a cell), it is considered neither eukaryotic nor prokaryotic. -
ANSWERTrue
Describe the two basic components of a virus. - ANSWERA virus has genomic material
made up of either DNA or RNA and a capsid which is a protective structure that
contains genetic material
