Microbiology W/ Lab EXAM QUESTIONS AND CORRECT
DETAILED ANSWERS| AGRADE (PORTAGE LEARNING)



Question 1 pts



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.


Co
orrrec
ct! True


False




Question 2 pts


Describe the two basic components of a virus.


Your Answer:

Two basic components of a virus are;




1/18

, The genomic material that comprises of either DNA or RNA
A capsid, a membraneus like protective structure that contains genetic
materials similar to those of the eukaryotic cell




A virus has (1) genomic material comprised of either DNA or
RNA and (2) a capsid, a membrane-like protective structure
that contains the genetic material, similar to the nucleus of a
eukaryotic cell.




Question 3 pts

Your Answer:

Capsid




capsid

, Question 4 pts


True or False. You would expect to see a viral envelope on a virus
infecting a bacterial cell.


True

Co
orrrec
ct! False




False. The overwhelming majority of animal viruses are enveloped
whereas the majority of plant or bacteria-infecting viruses are not.




3/18

, Question 5 pts



Rank the following viruses based on their size from largest to smallest:

Paramyxovirus

Poliovirus

Smallpox virus


Your Answer:

Smallpox virus(~200nm) ---> Paramyxovirus(100-150nm) --->
Poliovirus(~30nm)




Smallpox (~200nm) > Paramyxovirus (100-150nm) >
Poliovirus (~30nm)




Question 6 pts


True or False: Viral replication occurs after it attaches and enters the host
cell.


Co
orrrec
ct! True


True. The viral genome is never replicated before attachment and
entry.
