Most of us are missing so much because we can't see the bigger picture...
That the RNA is the catalytic part of the ribosome is well known. It’s basic.
My comment was simply to point it out, not to judge if someone should know or not.
Semiotics requires mind.
No gap there.
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.
Semiotics is simply the symbolic representation of meaning.
DNA = digital code = semiotics.
Semiotics requires mind.
In crude deductive form:
1. The origin of digital code requires a mind.
2. DNA is a digital code.
3. Therefore, the origin of DNA requires a mind.
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.
Re: It’s not arcane or esoteric anymore than knowing DNA is the genetic material or ATP is produced in the mitochondria.
I know exactly what DNA, ATP, and mitochondria are.
What I don’t know is how you selectively remove the protein structure of an organelle without destroying it.
I am looking forward to your helpful instruction.
RNA will form it’s own structure. Proteins are often associated.
RNA, unlike DNA, is very flexible.
In this case the proteins were removed with protease and SDS, a detergent. Neither affect RNA.

And, where are the ribosome structural proteins manufactured?
Just to be clear, I am not a religious person, and I find the Theory of Evolution to be very persuasive and very helpful.
However, the “chicken or egg” mystery of structural proteins in ribosomes has not been easily or compellingly explained.
It’s not compelling.
It would be if RNA were not the catalytic component.
What adaptive function did that serve since free floating cellular RNA apparently worked just fine before the structural proteins showed up?
