Abstract
Abstract
At the core of all living cells lies DNA, RNA, and protein - a deeply conserved communication architecture encompassing transcription, translation, the genetic code and the Central Dogma. No existing theory explains why this specific DNA-RNA-protein system exists or why it exhibits its particular structure. Here, communication is analysed in a substrate-independent regime, free of space, time, and matter, under logical constraints alone. A unique triadic, unidirectional architecture emerges: the Non-Physical Communication Architecture (NPCA). The NPCA maps directly to the DNA-RNA-protein system, thereby providing a unified account of the DNA-RNA-protein information flow as embodied logic rather than historical accidents of prebiotic chemistry. Life is defined as the embodied NPCA (E-NPCA) in matter. This framework resolves puzzles in viral classification, cryptobiosis and homochirality, while implying a rare, threshold origin of life with consequences for the Fermi Paradox.

Abstract
Abstract
The Central Dogma of molecular biology describes a fundamental asymmetry in biological information processing: there is no reverse translation. Despite its centrality, this asymmetry lacks a theoretical derivation. We show that DNA, RNA and protein embody a unified set of architectural constraints on communication, derived from minimal assumptions, which we term the Non-Physical Communication Architecture (NPCA). Within this framework, communication is necessarily triadic and unidirectional, culminating in a terminal receive-only mode. The absence of reverse translation therefore follows directly from the NPCA as an architectural necessity, rather than a contingent feature of biochemistry. This perspective reframes the Central Dogma as an expression of deeper logico-architectural constraints governing communication.
