摘要翻译:
本文主要研究斐波那契序列及其q变形或量子扩展在遗传密码研究中的相关性和应用可能性。首先,在提出一个新的公式后,由前6个Fibonacci数组成的索引双Fibonacci序列描述了20个氨基酸多重序列及其简并性,并给出了61个有意义密码子的特征模式。其次,根据原子数(碳、氮、氧和硫)的增加,这20个氨基酸呈现出几种斐波那契序列模式。给出了几种数学关系,描述了各种原子数模式。最后,用一个简单的唯象模型,以q为实形变参数,统一地描述了当q=1时的标准遗传密码,以及当q~1时的所有已知遗传密码的微小变异,以及当q~1时的第21个氨基酸(硒半胱氨酸)和第22个氨基酸(吡咯赖氨酸)的情况。作为这个基本模型的副产品,我们还表明,在极限q=0时,氨基酸的数量达到了6的值,这与古老的、仍然持续存在的说法是一致的,即生命在其早期发展中可能只使用少量氨基酸。

英文摘要:
This work aims at showing the relevance and the applications possibilities of the Fibonacci sequence, and also its q-deformed or quantum extension, in the study of the genetic code(s). First, after the presentation of a new formula, an indexed double Fibonacci sequence, comprising the first six Fibonacci numbers, is shown to describe the 20 amino acids multiplets and their degeneracy as well as a characteristic pattern for the 61 meaningful codons. Next, the twenty amino acids, classified according to their increasing atom-number (carbon, nitrogen, oxygen and sulfur), exhibit several Fibonacci sequence patterns. Several mathematical relations are given, describing various atom-number patterns. Finally, a q-Fibonacci simple phenomenological model, with q a real deformation parameter, is used to describe, in a unified way, not only the standard genetic code, when q=1, but also all known slight variations of this latter, when q~1, as well as the case of the 21st amino acid (Selenocysteine) and the 22nd one (Pyrrolysine), also when q~1. As a by-product of this elementary model, we also show that, in the limit q=0, the number of amino acids reaches the value 6, in good agreement with old and still persistent claims stating that life, in its early development, could have used only a small number of amino acids.
