In the first article ( here ), we have explored what Turing patterns means in a biological sense by given examples of how it occurs in nature. The series of the articles is building up to genetically modifying organisms to forward engineer Turing patterns. But first, a clear understanding of genes and gene regulatory networks must be given. Gene Anatomy At a crude level, in any living organisms –with some rare few exceptions–, The DNA acts as the blueprint for computations performed in the cell. It consists of nucleic acid monomers linked together to form polymer chains . There are four main types of nucleic acids, adenine (A), guanine (G) cytosine (C), and thymine (T) [3]. DNA molecules usually come in double-helix strands of polymer chains, as shown in figure 1. The two polymer chains are linked together via hydrogen bonds in the given structure: an adenine (A) base is always linked to a thymine (T) base, and cytosine base (C) is always linked to a guanine (G) base.
