You don’t need to understand the meaning, as long as you string together a few science terms you learned in grade school, it must be true.
Do I really need to say it? Being injected with an RNA vaccine does not replace your entire nuclear genome with RNA.
Although…it does make me wonder what would happen if a magic enzyme added a hydroxyl group to all your ribose sugars to convert DNA to RNA. Yeah, changing the chemical properties of all of your chromosomes to make them more labile and prone to rapid breakdown and unrecognizable to most of the key proteins for transcription, among other things, would be kind of catastrophic and thermodynamically costly.
There’s probably some vicious Hebrew abuse going on there, too, but I wouldn’t know.
Wait, does this mean that when you die, your soul retains some kind of DNA-based organic structure?
No, stop, don’t over-think this. Trying to puzzle out serious meaning from that text leads to madness.
