Microbiology Module 6 Portage
Learning Exam Questions and
Answers 100% PASS
True of false: Because the genome is contained within an enclosed space (much like the
nucleus of a cell), viruses are classified as eukaryotic.—ANSWER-False
Describe the two basic components of a virus.—ANSWER-1) Genomic material made up of
DNA or RNA
2) Capsid, which is a membrane like protective structure that contains genetic material.
The _____ surrounds the capsid of some viruses.—ANSWER-envelope
True of false: You would expect to see a viral envelope on a virus infecting a plant cell.—
ANSWER-False
Rank the following viruses based on their size from largest to smallest:—ANSWER-
Variolavirus; orthomyxovirus; poliovirus
True or false: Viral replication occurs after it attaches and enters the host cell.—ANSWER-
True
, Place the following viral life cycle in order beginning with viral attachment and provide a
description of each step.—ANSWER-1. Attachment: viral receptors bind to host proteins on
the surface of the cells
2. Entry: virus fuses w/host cell membrane and enters the cell
3. Uncoating: viral capsid disassembles
4. Replication: viral genome is the blueprint to make copies of itself
5. Release: new virus are produced and leave the cell
6. New infection: newly produced viruses that left the host cell now go on to infect new
cells.
A virus that infects bacteria is called a [answer 1] and contains a [answer2] sided polygon
capsid.—ANSWER-Bacteriophage; 20
True or false: Structurally, bacteriophages are similar to viruses that infect animals.—
ANSWER-False
Describe the main differences between lytic and temperate phages.—ANSWER-Lytic:
bacteriophages replicate within the host bacteria until it ruptures, whereas temporate
phages primarily exist in a non-replicative state that doesn't kill the host cell..
Lytic phages replicate the viral proteins needed for the assembly of new virus particles
whereas lysogenic phage genomes are integrated into the host genome but production of
viral proteins is suppressed.
