Unit 5: Viruses Flashcards
What are the three phases of integration during lysogenic replication?
combination
dormancy
reactivation
Which line of defense does your immune system fall within?
3rd
What type of virus is this?
icosahedral
What type of virus is this?
helical
What are the 5 phases of lytic replication?
attachment
penetration
synthesis
assembly
release
Which type of genetic recombination involves a virus?
transduction
Which line of defense does your skin fall within?
1st
Which type of viruses attacks animals
icosahedral viruses
Virues are extremely small, smaller than bacteria so they are known as….
submicroscopic
What is found inside of a virus?
Nucleic acid
(RNA or DNA)
In latin virus means….
poison
Which line of defense targets a specific pathogen?
3rd
For a virus that hides out in the body, where does it re-enter lytic replication?
at the synthesis phase
Since viruses are inactive outside of host cells and must invade cells in or to be active, they are known as
pathogens or parasites
What is the outside most layer of an animal virus
envelope
Which structures of a virus allow it to attach to a host cell?
Surface proteins of the capsid or envelope
(like a lock and key with host cell’s surface proteins)
What type of virus is this?
bacteriophage
Which line of defense does a fever fall within?
2nd
(inflammatory response)
Which type of viruses attacks bacteria?
bacteriophage
What is a nucleic acid core surrounded by a proten coat called?
a virus
All viruses begin with which type of replication as they infect a cell?
lytic
For a virus such as HIV, where during the lytic process does it leave and enter into lysogenic replication
It leave lytic after the penetration step and enter at combination in lysogenic
How many lines of defense are there within your body?
3
Which type of viruses attacks plants?
helical viruses
