CORRECT VERIFIED ANSWERS. A+
GRADED
True or False. Because the genome is contained
within an enclosed space (much like the nucleus
of a cell), viruses are classified as eukaryotic -
>> correct answer >>False. Viruses are neither
eukaryotic nor prokaryotic.
,Describe the two basic components of a virus. -
>> correct answer >>1. genomic material
comprised of either DNA or RNA
2. a capsid: membrane-like protective structure
that contains the genetic material
The envelope surrounds the _________ of some
viruses. - >> correct answer >>capsid
True or False. You would expect to see a viral
envelope on a virus infecting a bacterial cell. -
>> correct answer >>False. The overwhelming
majority of animal viruses are enveloped
, whereas the majority of plant or bacteria-
infecting viruses are not.
Rank the following viruses based on their size
from largest to smallest: Orthomyxovirus
Poliovirus
Variolavirus - >> correct answer >>Variolavirus
(~200nm) > Orthomyxovirus (100-150nm) >
Poliovirus (~30nm)
True or False: Viral replication occurs after it
attaches and enters the host cell. - >> correct
