| Describe the mechanism of "PHAGE?" |
|
Definition
Temperate Phage: Stable in bacterial cell
Next, after integration into the bacteria DNA Genome, it becomes a Prophage.
Now two fates:
1. Either remain in cell as PROPHAGE
2. Produce Virulence factors to increase disease prospect. This is known as:
Lysogenic Conversion |
