Hmm. I can believe it, but I can’t trust them about what ELSE it does. If they know at all.
Then they can be “trained” to kill ANY cells.
Spot on. 'Specific' binding of anything in the body is predicated on random interactions and whether or not those interactions result in a favorable energy state for the interaction. Molecules, including DNA, RNA, and nanobots don't have a 'GPS' system that brings them specifically to their preferred target. They just bounce around interacting with whatever they encounter - until they bind to something that leads to a more favorable molecular energy state together rather than apart.
Such molecules, nanobots etc might interact with a significant number of other molecules/targets before finding the right one, and could have a stable-enough energy state binding to off-target molecules/cells/etc such that they remain attached long enough to have deleterious effects/off-target effects.
This is why a lot of molecules that have specific binding targets are unstable - remaining viable just long enough to have a chance to find the appropriate target, but not so long such that they build up and start binding the next best targets with regards favorable binding energy.
Anyway, it's a cool start.
Yep, that’s the big question. What else can it be made to do. Cancer is too big of a business to simply shut the doors on that $$$$$.
Listen closely to beginning of “Legend”.
