Right back where we started.
Just like the author, I am saying that the ribosome organelle is constructed out of proteins.
You said that when all the proteins are removed from the ribosome structure, it still functions normally.
That sounded pretty weird - like, you can take all the support columns out of a building, but it won't fall down.
However, since I am not a biologist, I agreed to take your word for it.
A claim like that might pass for “common knowledge” in your universe, but not in mine.
You’re not writing articles about biology. Which makes sense.
It’s not arcane or esoteric anymore than knowing DNA is the genetic material or ATP is produced in the mitochondria.
