Oh, I didn't mean it would be simple, I meant: (simple roman coding), as in the easiest encryption there is.
I was wondering about it, because:
- printing genes is already possible. With advancements in this field, it's not unthinkable that (many years from now) an entire genome could be printed
- the translation to proteins is, as far as I understand, established by "translation molecules" that bind to three particular letters
- if you change the DNA, and change the corresponding "translation molecules", the system would behave identically.
- this new organism would still make the old, non-coded translation molecules, so you'd need to fix that too.
I don't expect this to be easy, maybe it's even impossible, how would I know? I'm no expert. It's just a thought experiment. But if you could do such a thing, would it be good or bad? Viruses that have co-evolved with us would never be able to adapt to that, I think.
Also, could such an embryo be implanted into a mother and survive? I think it would, the cells would be the same, the immune system does not deal directly with DNA.
Anyway, that's just me pondering on some far-out ideas, I hope you don't mind :-).
