Viral Repro. (AEISVR)
Lytic vs. Lysogenic
Role of RNA
Binary Fission
100
Name the first stage of viral reproduction. 
A- Attachment 

Binds to proteins in the outer membrane. 

100
What is the lytic cycle? 
a phage replicative cycle that culminates in the death of the host cell. 
100
What is Reverse Transcriptase? 
Forms DNA from an RNA Template in reverse transcription. 
100
What is binary fission?
A division of cells in half (asexual reproduction) 
200
Name the second step of viral reproduction. 
E- Entry 

Injects the virus DNA into the cytoplasm of the cell. 

200
A phage that only reproduces by the lytic cycle is called _____. 
virulent phage 
200
Can a RNA test reveal a virus in someones blood? If so, why? 
Yes, because it will detect the virus in your blood at an early stage. 
200
The divided cells are ____ to the parent cell. 
Identical 
300
What stage is associated with the lytic cycle? 
S- Synthesis of viral components 

phage DNA directs the synthesis of viral components. Phage DNA circularizes, host chromosomal DNA degraded. 

300
What is the lysogenic cycle? 
replicates the genome without destroying the host. 
300
What does RNA not do? 
Proofread
300
What is Transduction?
An error in the lytic cycle, bacteria transfers genetic material to another 
400
What is a capsid? 
Protein shell that encases the viral genome. 
400
Name 2 similarities and differences between the lytic and lysogenic cycles.
Lytic destroys host cell, lysogenic does not 


Lysogenic genome links to chromosome as a prophage, and is replicated to daughter cells and can initiate a lytic cycle. 

Phage DNA circularizes for both

Both replicate.


400
True or false: RNA is not required to make DNA. 
False. 
400
What is the difference between horizontal and vertical gene transfer? 
Horizontal= Between Species 

Vertical= Generational

500
Name all the stages of the viral reproductive cycle. 
A- Attachment 


E-Entry 

I-Integration

S-Synthesis 

V-Viral assembly

R-Release 

500
Phases that use both lytic and lysogenic are called 
Temperate phages 
500
Can a virus carry HIV?Why? 
Yes, because it is stored in the virus' genetic material. 
500
Name the three steps of Binary Fission
1. Conjugation 

Physical interaction transfers genetic material from donor to recipient cell 

2. Transformation

Foreign bacteria introduced. 

3. Transduction 

Error in lytic cycle where genetic material from bacteria is tranferred.
