BIOD 171 Essential Microbiology Portage Learning Module 6
Correct!
False. Viruses are neither eukaryotic nor prokaryotic.
False
True
True or False. Because the genome is contained within an enclosed space (much like the nucleus of a cell), viruses are classified as eukaryotic.
Question 1^ 2 / 2 pts
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.
Your Answer: Two basic components of a virus the genomic material comprosed of either DNA or RNA and a capsid, which is the membrane or protective coat that contains the genetic material
Describe the two basic components of a virus.

BIOD 171 Essential Microbiology Portage Learning Module 6 Exam Questions and Answers
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: Viral receptops bind to host proteins on surface Entry: Virus fuses with host membrane and enter cell Uncoating: Capsid disassembles Replication: Viral genome create blueprint to make copies of itself
Exit: New viruses are produced and exit the cell
New Infection: newly produced viruses leave the host cell and travel to infect other cells and then the whole process begins again
3- Uncoating: the viral capsid disassembles
5-Release: New virus particles are produced and leave the cell 4- Replication: the viral genome is the ‘blueprint’ to make copies of itself 1-Attachment: viral receptors bind to host proteins on the surface of the cell 2-Entry: the virus fuses with the host membrane and enters the cell 6-New infection: newly produced viruses that left the host cell now go on to infect new cells.

Jonas Salk and his research team developed the polio vaccine at the University of Pittsburgh in 1955.
Influenza A
Your Answer: FLU A or Influenza A
Which subtype of Influenza is the most virulent?
Question 25^ 3 / 3 pts
Hemagglutinin (HA) proteins would be targets as they are directly involved in viral attachment and entry into the host cell. Neuraminidase proteins are involved in the budding and release of new viral particles and would thus not be the correct target.
Your Answer: The drug company would target HA or hemagglutinin proteins because they are directly involved in viral attachment and entry into host cells.
A drug company is trying to develop a new drug that will inhibit viral entry of Influenza. Would the drug company target hemagglutinin proteins or neuraminidase proteins? Why?

Question 29^ 2 / 2 pts
Answer: As the name suggests, anti-retrovirals are intended to inhibit (anti) the life cycle of retroviruses (retro). By inhibiting steps in the HIV’s lifecycle, anti-retroviral medications effectively block the production of new virus particles and lower the viral load of the patient.
Your Answer: The general purpose of this medication is to inhibit the process of reverse-transcription -- that is to reduce the amount of HIV in the blood to very low levels and suppress the virus.
An individual infected with HIV is placed on anti-retroviral medication. What is the general purpose of this medication?
