I think the folding/etc would all be mirrored as well if all the components were on mirror-chirality and the overall molecular-kinetic behavior of the result would in-theory be the same when zoomed-out too (assuming it doesn't encounter too many normal-chirality molecules I guess - would be just as dangerous to them as mirror-chirality is to us).

This should mean that if the DNA is mirror (no need to alter the sequence), and the RNA/proteins/etc are as well (like 100% made of the mirror-chiral molecules), then in isolation it might work just the same as regular-life, just twisting the other way?

Kinda does seem like it might be a bit arbitrary what direction things should curl in, however there are maybe aspects of how quantum-spin might interact with things that might rule out stability with mirror-chirality? I am not a QM scientist but I do find it very fascinating!
