I mean, my point is that "if (race == whatever)" is completely nonsensical from an mRNA perspective.

There's no way for mRNA to scan the rest of your DNA sequence to make an if/else determination. mRNA is just gonna execute once its in the body.

Yeah, that's called a poison and antidote / antitoxin. You don't need mRNA for that. Poison someone's food, and as they lie dying, you can offer them the antidote in exchange for something.



Also, one would have to define "race" in genomic terms. Good luck to the person attempting to do that.


Is that really that hard? A $100 genetic test will tell you what race(s) you are.


Will it? Sure, you can predict from where your ancestors came, haplotype, etc.

But define race in a genomic sense. It's a feat that key genomic experts have not yet been able to accomplish. For instance: http://ewanbirney.com/2019/10/race-genetics-and-pseudoscienc...

Is it? mRNA can code for a protein that detects other mRNA in the same cell, which may reflect any genetic characteristic of the host.


mRNA isn't really code. Its a blueprint.

When we say mRNA "executes", that's a cell injesting mRNA, and assembling a protein (polypeptide). For example, the mRNA sequence 'ACU', when 'executed' by a cell, will turn into a Threonine: https://en.wikipedia.org/wiki/Threonine


RNA can fold up and get stuck to other sequences. Using that as a trigger isn't out of the question.

Of course there is, genes can be turned on/off using transcription factors. Still, the sequence of vaccines are published and easy enough to sequence and analyze, so I don't think something like this could be mass produced.
