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


The envelope surrounds the of some viruses.


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.

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.


3/18

, False




Question 7 pts



Place the following viral life cycle steps in order beginning with viral
attachment and provide a description of each step.

Uncoating:

Release:

Replication:

Attachment:

Entry:

New infection:




Your Answer:

Attachment --> Entry --> Uncoating --> Replication --> Release --> New
Infection

Attachment; the viral receptors attaches to te host protein on the cell
surface
Entry; the virus fuses with the membrane of the host cells and enters
the cell
Uncoating; The viral capsid disassembles
Replication; the viral genome is the blue print that replicates itself
Release; New viral particles are produced and then released
New Infection; the released new viral particles that exists the cell go
ahead and infect new cells
