The processes associated with biological systems are characterized by their high complexity, specificity and efficiency, due to the great variety of mechanisms that participate in them. The process of synthesis of proteins is considered for the cell a key of biological functionality, considering that the protein machinery promotes the great majority of functional processes in biological systems. The central dogma of molecular biology is the mechanism that defines the flow of DNA-RNA-Amino Acids-Proteins gene information, involving the processes of transcription, translation and synthesis. Furthermore, the cell can generate control mechanisms to regulate its own processes in response to intrinsic or extrinsic interactions. Considering the functionality of the processes related to the synthesis and regulation of proteins in biological systems, in this work we developed a genetic algorithm with the potential to optimally solve an engineering problem. The proposed engineering problem is to find the PID controller that has the best performance for the position control of a DC motor. The solution to this problem showed that better results can be obtained with the optimization algorithm proposed in this work than the results obtained from classical tuning techniques.
