What accounts for that "arrangement" or 'specificity' is the question
But where that code symbol system comes from is what has to be explained
Appealing to just "physics" is not an explanatory answer.
Appealing to just "physics" is not just *an* explanation, it is *the* explanation, and is the only explanation with any explanatory power at all in this universe.
Where did the various nucleotides and amino acids come from?
How did the various groupings of 3 nucleobases achieve their connections to the various amino acids?
How did any millions of molecules and their reactions to others come to exist?
Physics. Specifically, quantum field theory. More specifically, chemistry. And a good deal of evolution which is even more physics piled on that.
When we look out into space we find thousands of molecules just floating around naturally formed in the interstellar medium. Of the thousands of molecules we have detected out there the vast majority of them are organic molecules, and include a couple simple amino acids, partial ribo- and dioxyribo- phosphate groups and amino and nucleotide precursors.
From our lab experiments we KNOW with certainty that these molecules on an early earth could combine into ever more complex molecular structures by the force of chemistry alone.
If you want specific atom-by-atom bond-by-bond details of these experiments and their results then consult a chemist.

We do not know, yet, how the first replicators came to be. I certainly don’t and neither do you. Since every solved we don’t know, yet problem that humans have ever come across was resolved by a physical system there is no reason to pre-suppose otherwise for all our remaining ignorance.
But we do know how evolution works. We understand the physics of replication and selection. We understand the power of trillions upon trillions of trials and failures each moment over billions of years of evolution. All naturally achieved. All by the natural processes of chemistry. All by nothing but physics.
Other than the personal incredulity of the ignorant there is no reason to conclude that the aminos, nucleobases and all the chemistry cascades associated with each that we have been talking about came to be by any other than natural physical means.
Of all the trillions upon trillions of trials and failures each moment over billions of years of evolution, finding a few dozen chemical cascades that grew to work well and consistently in the complex life systems we see on this planet is not difficult to justify. Evolution works. So does physics.
Once the chemical processes are in place and operating consistently in every cell in every living thing it should be no surprise that some smart monkeys would come along with test tubes and pipettes and charts and graphs to document each of the molecules, their interactions and the consistent nature of their operations.
Bobo make’t information.
It may be more difficult than rocket surgery owning to the complexity involved but we really are super smart monkeys.
Once all the monkeys stopped arguing over the forms, names and numbering of the charts and graphs, the consistent repetitious pattern of nucleobase codons and their chemistry became clear.

At Percy's request I accept the word code and accept that information has more popular connotations than it should.
In the end what Bobo found was a genetic code, information that symbolically reduces to specific chemical results.
The chemistry did not create the code. The code is mere description of the chemistry as perceived by Bobo.
That code was born from the charts and graphs Bobo made observing the physical chemistry in action. And that chemistry in action was born from the physics of evolution. Nowhere else.

Physics. Only physics. Exclusively physics. Nothing more. There is no reason to suggest otherwise.
But the symbol system is integral to the process ...
No, it is not.
Adenine came from natural chemical processes. The codon AUG results in a methionine amino added to the protein chain. The symbology of the code means nothing. The process is purely rote chemistry and came about from trillions of trials over billions of years.
... and for answering the "why", and physics doesnt explain the symbol system, nor where the configuration of x came from
The "why" is because after trillions of trials over billions of years *that* is what worked.
Physics doesn't need to explain the the symbol system. The symbol system is a direct picture of the physics. The symbol system explains the physics.
So you are here at least admitting that there are external copies of something (form matters not) that carries a symbolic meaning. This is all external to the mind.
I never denied symbology external to the mind. But I insist that symbology be embedded in a physical system. And while I will allow such symbology to be popularly called "information" I further insist that all symbology can only represent and be copied from that which originates in the mind.
