Portage Learning Microbiology Module 6
Exam 2026 Questions and Answers
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 or proaryotic
Describe two basic componenents of a virus - Correct answer-1. A virus has
genomic material: meaning it is comprised of either DNA or RNA2. A virus will
have a capsid; a 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 envelop on a virus infecting a plant
cell - Correct answer-false. the overwhelming majority of pant or bacteria-infecting
viruses are not

, true or false: highly infectious viruses undergo genome replication prior to viral
attachment and entry - Correct answer-false. the viral genome is never replicated
before attachment and entry regardless of its level of infectivity
"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 - Correct answer-"1. Attachment: viral receptors bind to host
protiens onthe surface of the cell
2. Entry: the cirus fuses with the host membrane and enters the cell
3. Uncoating: the viral capsid disassembles
4. Replication: the ciral fenome is the blueprint to make copies of itself
5. Release: new virus particles are produces and leave the cell
