You have explained nothing. You are the perfect example of explanations that are not explanations at all.
How does knowing "the key bits of viruses that contribute to pathogenesis" save lives? Once you know that, what are you going to use that knowledge for? How does it help?
I need to build nuclear bombs so I can understand how deadly they can be. How am I helping ...[text shortened]... s an answer.
Once again, how does that help people?

If you know what triggers the mutation, you can create counter-measures.
Imagine, if you will virus X-2.34
This is a virus in a second mutation in a 34th variant of that second mutation.
With me so far?
Now, say virus X-1 was far less deadly than virus X-2.
What you want to know is if virus X-2 mutates into X-3, if it will be more or less dangerous. You want to know what triggers that mutation (why not just a sub-mutation) and you want something that will counter-act as many mutations as possible.
The first step is check out the basic building blocks of X. Maybe there’s something there, that if you counter-act that, it will be an effective counter-measure for all mutations.
When that’s not the case?
You can try to recognise patterns in the mutations so you can reasonably counter-measure future mutations.
If there’s no reasonay distinct pattern? You have to discover triggers, etc.
That means grabbing virus X or X-2 by the scrotum and squeezing until you see what happens. Do it 10 times with the same result, then there’s a chance you can create counter-measures.
Etc.
It’s not a difficult concept. What they do in the lab obviously is, but basically the concept is the same as a car mechanic fixing a car.
Or maybe it’s an evil genius plotting world domination by pizza hut.
