 A gene plays a central role in morphogenesis, the creation of body structures, which successively is central to evolutionary developmental biology. The regulator are often DNA, RNA, protein and complexes of those.  The interaction are often direct or indirect (through transcribed RNA or translated protein).  Generally, each mRNA molecule goes on to form a selected protein (or set of proteins). In some cases this protein are going to be structural, and can accumulate at the cell wall or within the cell to offer it particular structural properties. In other cases the protein are going to be an enzyme, i.e., a micro-machine that catalyses a particular reaction, like the breakdown of a food source or toxin. Some proteins though serve only to activate other genes, and these are the transcription factors that are the most players in regulatory networks or cascades. By binding to the promoter region at the beginning of other genes they turn them on, initiating the assembly of another protein, and so on. Some transcription factors are inhibitory.
