Question

What can trigger the Lysogenic cycle (dormant virus) to go into the lytic cycle (active virus)?
SELECT TWO ANSWERS
Select all correct options
Chemicals
Lack of Food
Cell Transport
Photosynthesis

Answer 1

The two factors that can trigger the lysogenic cycle to switch to the lytic cycle (where a dormant virus becomes active) are:

1. Chemicals - Certain chemicals can induce stress on the viral genome, activating the expression of viral genes that lead to the lytic cycle.

2. Lack of Food - Nutritional stress or environmental factors that lead to lack of resources for the host cell can trigger the lytic response as the virus seeks to replicate and spread before the host cell dies.

The other options, "Cell Transport" and "Photosynthesis," do not directly relate to the triggering of the lysogenic to lytic cycle in viruses.
