title: The origin of life. A cybernetic and informational process.
abstract: According to the model presented in this paper, the beginning of life was marked by the coupling of two complementary nucleotide bases: adenine and thymine. The adenine-thymine system received photons from the sun and stored their energy in the form of a chemical high-energy bond between two phosphoric acid molecules, which were before-hand fixed by adenine from the aqueous environment. The energy of the high-energy bond was then delivered in the form of two waves of electronic excitation. These were utilized to synthesize new molecules, starting from the carbonic acid and ammonia molecules, fixed from the aqueous environment by the polar groups of the nucleotide bases. In this way, a nucleotides-histone protosystem (NHPS) was self-synthesized, evolving step by step towards complexity, by means of some internal cybernetic and informational mechanisms. During its evolution, the NHPS synthesized a limiting membrane, produced the organizing elements of the cellular organelles (chloroplastes, mitochondria, ribosomes etc) and constructed microtubules and microfilaments. Subsequently, the NHPS evolved to the building of DNA-histone system and formed the cellular nucleus.
