Before revision:  Molecular biology assumes that function is explained by structure, the complementary geometries of molecules and weak intermolecular hydrogen bonds. However, both this assumption and its converse are possible URLanic molecules and quantum circuits/protocols are considered as hardware and software of living systems that are co-optimized during evolution.
After revision:  Organic molecules and quantum circuits/protocols are considered as hardware and software of living systems that are co-optimized during evolution.
