Recently the terms “codes” and “information” as used in the context of molecular biology have been the subject of much discussion. Here I propose that a variety of structural realism can assist us in rethinking the concepts of DNA codes and information apart from semantic criteria. Using the genetic code as a theoretical backdrop, a necessary distinction is made between codes qua symbolic representations and information qua structure that accords with data. Structural attractors are also shown to be entailed by the mapping relation that any DNA code is a part of (as the domain). In this framework, these attractors are higher-order informational structures that obviate any “DNA-centric” reductionism. In addition to the implications that are discussed, this approach validates the array of coding systems now recognized in molecular biology.

DNA 代码和信息：形式结构和关系原因

最近，分子生物学中使用的术语“代码”和“信息”成为了很多讨论的主题。在这里，我建议各种结构现实主义可以帮助我们重新思考除语义标准之外的 DNA 代码和信息的概念。以遗传密码为理论背景，对作为符号表示的代码和作为符合数据的结构的信息进行了必要的区分。结构吸引子也被证明是由映射关系所包含的，任何 DNA 代码都是其中的一部分（作为域）。在这个框架中，这些吸引子是高阶信息结构，可以避免任何“以 DNA 为中心”的还原论。除了所讨论的含义之外，这种方法还验证了现在分子生物学中公认的一系列编码系统。
