ABSTRACT
Reproductive material units, such as molecules and cells, emerge as a consequence of the successive feedback from product to production. Molecular and cellular reproduction is a nonanthropomorphic information processing. Nonanthropomorphic information processing that permits the preceding products to be the boundary conditions for the subsequent production gives rise to what looks like a reproductive or protoreproductive process. Molecular replication and cellular multiplication are inseparable from each other when they function in contemporary biological systems. The genetic code apparatus is a very specific form of interdigitation of various reaction cycles of both polypeptides and polynucleotides. The intrinsic chemical affinity between amino acids and nucleotides underlies the presence of interdigitated reaction cycles of polypeptides and polynucleotides. Molecular replication that can enhance its reproductive fidelity with time necessitates the endogeneity of boundary conditions in the sense that the intake of resources is internally regulated just so as to respond to what is actually required in the molecular synthesis.
