Abstract

Molecular codes can be considered a special type of mapping among molecular species in biochemical systems. The formalization of molecular codes allows to identify these in network models of real world systems. Analyzing algorithmically identified codes leads to the observation that codes does not necessarily stand alone, but that we can identify certain relations among codes. In this paper I will define two types of relations that can occur among codes, code linkage and code nesting, and will discuss implications of this finding
