This paper shows how biological design in bacteria chemotaxis control shows architectural design features that are found in many areas of biological life that reflect an engineering framework found in the creation model. The study highlights the bacteria chemotaxis control process utilizing the System Modeling Language (SysML) to leverage well-defined and proven engineering tools for architecting, analyzing, and refining complex systems. It first introduces SysML, and the advantages model-based systems engineering (MBSE) has for capturing system architecture and allowing for ongoing assessment of how biological system operates and the clarification of how much model detail is required to reveal a system element function. Then using SysML modeling methods, the chemotaxis control process is captured. Details of the chemotaxis control process are captured in SysML syntax instead of a biological syntax. This approach intentionally enables the analysis of the biological chemotaxis control system from an engineered system point of view. After the functional model is analyzed, the resulting insights and observations are discussed. The model can act as a scaffolding to help uncover system function, the relationship of system components and processes, and bioinformatic phenotype and genotype correlation.
