Hen and egg problems of biology from TGD point of view

Biology has several hen and egg problems. What came first: DNA,RNA, amino-acids or proto-cell membrane? Did metabolism precede genetic code or vice versa? The stimulus leading to this article could have been the finding that organic molecules are formed in interstellar space at ultralow temperatures of few Kelvin in which chemistry should freeze completely. Therefore the formation of glycine peptides, which has been demonstrated in the laboratory, should be impossible. The paradox disappears in the TGD framework as do also the hen and egg problems. Magnetic body carrying dark matter as $h_{eff}=nh_0$ phases allows a universal realization of genetic code and of the analogs of basic bio-molecules in terms of dark nucleon and dark photon triplets. Chemical realization emerged later and the question is whether they emerged simultaneously or whether there was some natural order for the chemical steps. The prebiotic form of metabolic machinery based on hydrogen bonds and dark protons emerged at the same time. A metabolism with metabolic energy quantum assignable electrons which corresponds to average energy of a photon of microwave background is predicted and shows itself via miniature potentials of the neuronal membrane
