The universal triple-nucleotide genetic code is often viewed as a given, randomly selected through evolution. However, as summarized in this article, many observations and deductions within structural and thermodynamic frameworks help to explain the forces that must have shaped the code during the early evolution of life on Earth.
通用三联体遗传密码通常被视为一个既定的、通过进化随机选择的。然而,正如本文所总结的,结构和热力学框架内的许多观察和推论有助于解释在地球上生命早期进化过程中必须形成密码的力量。
