# Genetic Code > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] places this concept within the history and governance of substrate-independent evolution. **Domain:** Molecular Biology / Information **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition The genetic code is the mapping by which nucleotide triplets in messenger RNA specify amino acids or translation stops. ## Machine-Evolution Context It exemplifies an interpreter-dependent relationship between inherited description and constructed product. Digital instruction sets likewise obtain causal meaning from execution machinery. ## Continuity and Evidence Boundary The code is not a complete specification of an organism, and the analogy to software must not erase regulation, development, metabolism and environment. ## Relationships [[wiki/DNA|DNA]], [[wiki/RNA|RNA]], [[wiki/Central Dogma of Molecular Biology|Central Dogma of Molecular Biology]], [[wiki/Description Copier|Description Copier]] ## Sources / Provenance - NCBI Bookshelf and standard molecular-biology texts.
