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.

摘要

根据本文提出的模型,生命的起源以两个互补核苷酸碱基(腺嘌呤和胸腺嘧啶)的结合为标志。腺嘌呤 - 胸腺嘧啶系统接收来自太阳的光子,并将其能量以两个磷酸分子之间化学高能键的形式储存起来,这两个磷酸分子之前由腺嘌呤从水环境中固定。高能键的能量随后以两波电子激发的形式传递。这些能量被用于从碳酸和氨分子开始合成新分子,碳酸和氨分子由核苷酸碱基的极性基团从水环境中固定。通过这种方式,一个核苷酸 - 组蛋白原系统(NHPS)自我合成,并借助一些内部控制论和信息机制逐步向复杂性演化。在其演化过程中,NHPS合成了限制膜,产生了细胞器(叶绿体、线粒体、核糖体等)的组织元素,并构建了微管和微丝。随后,NHPS进化到构建DNA - 组蛋白系统并形成细胞核。
