By “use itself to muster a defense” you mean increase its mutation rate in order to ‘find’ genetic solutions to the stress?
Error prone DNA polymerase is expressed via transcription factors that are activated during the stress response. It is DIRECTLY involved in the actual response made to the stress because it DIRECTLY introduces mutations that ARE the response that is made.
The process IS established prior to the stress.
Why, are you ignorant enough to STILL insist that all cell stress leads to cell death?
Nope. You obviously cannot establish that every cellular response to a stress involves the use of error DNA_polymerase in the solution. Specifically, the example from slide 22.

Why are you so stupid as to not admit it was a distractor. That is why I placed, "Be that as it may" immediately subsequent to that statement. It is a definition question in my opinion. If you wish to define a stress as anything that provokes a response to it as stress that is fine. If you wish to define a stress as something that is harmful to the organism that is also fine, but I will not give up my French Fries or coconut oil because you think them stressful.
