EarthLife Genesis From Aromaticity/H-Bonding
Purines and pyrimidines are two of the building blocks of nucleic acids. Only two purines and three pyrimidines occur widely in nucleic acids.
Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring.
A purine is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Purines, including substituted purines and their tautomers, are the most widely distributed kind of nitrogen-containing heterocycle in nature.
Aromaticity ( Kekule, Loschmidt, Thiele) is essential for the Krebs Cycle for energy production.
Natural selection is E (energy) temporarily constrained in an m (mass) format.
Natural selection is a universal ubiquitous trait of ALL mass spin formats, inanimate and animate.
Life began/evolved on Earth with the natural selection of inanimate RNA, then of some RNA nucleotides, then arriving at the ultimate mode of natural selection – self replication.
Aromaticity enables good constraining of energy and good propensity to hydrogen bonding. The address of Earth Life Genesis, of phasing from inanimate to animate natural selection, is Aromaticity.Hydrogen Bonding.
