DNA contains the genetic code, which provides complete information about the synthesis of proteins in every living cell. Each gene encodes for a corresponding protein but most of the DNA sequence is non-coding. In addition to this non-coding part of the DNA, there is another redundancy, namely a multiplicity of DNA triplets (codons) corresponding to code for a given amino acid. In this paper we investigate possible physical reasons for the coding redundancy, by exploring free energy considerations and abundance probabilities as potential insights.

寻找遗传密码的物理基础。

DNA包含遗传密码，该密码提供有关每个活细胞中蛋白质合成的完整信息。每个基因编码一个相应的蛋白质，但是大多数DNA序列是非编码的。除了DNA的这个非编码部分外，还有另一个冗余，即对应于给定氨基酸编码的多个DNA三联体（密码子）。在本文中，我们通过探索自由能的考虑因素和丰度概率作为潜在的见解，研究了编码冗余的可能物理原因。
