ANSWERS GRADED A+
● Describe two basic componenents of a virus. 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.
Answer: capsid
● true or false: you would expect to see a viral envelop on a virus
infecting a plant cell. 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. 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. 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
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 _______ and contains a ____-
sided polygon capsid. Answer: bacteriophage, 20
● True or False: Structurally, bacteriophages are similar to viruses that
infect animals. Answer: False. Bacteriophages have a distinct
composition and structure
● Describe the main differences between lytic and temperate phages.
Answer: Lytic bacteriophages replicate within the host bacteria until it
ruptures, where as temperate (or lysoenic) phages primarily exist in a
non-replicative state that does not kill the host cell
