What are the 6 stages of viral reproduction?
- Attachment
- Entry
- Integration
- Synthesis of Viral Components
- Viral Assembly
- Release
If a host cell is dividing and the daughter cells also contain a prophage, what cycle is the virus in?
lysogenic
What are the stages of the lytic cycle in simple terms?
Attach to the cell, enter the cell, kill the host cell and produce phage offspring, leave via lysis
prophages can remain dormant for a long period of time thanks to the ________ cycle
lysogenic
What is the main type of factor that can change a phage from a lysogenic cycle to a lytic cycle
environmental factors
What are two types of cells that play a major role in HIV DNA incorporation?
Integrase and Reverse Transcriptase
HIV virus uses what type of receptor site?
CD4 and CCr5
What type of cell is mainly affected by HIV viral infection?
Helper T-Cells
Temperate Phage?
A phage that can spend some of its time in the lysogenic cycle
Virulent Phage?
A phage that can only follow that lytic cycle
Why is there a high mutation rate within the HIV virus?
The HIV virus cannot proofread
