        <p class="contentP">Since its inception more than a decade ago, synthetic biology has undergone considerable development and has attained significant achievements with the help of the engineering slant. However, there are still obstacles to build a cell. Engineers try to abstract the DNA sequences into some standard functional parts and assemble them using some principles in electrical engineering. So far, the limited understanding of biological system prevents us to combine parts and modules to create larger scale systems. The complexity of synthetic systems didn’t increase rapidly as the Moore’s law (Purnick and Weiss, 2009). </p>

    • 1. Parts

    Cells sense the environment, process information, and make response to stimuli. To make cells work well in complex natural environments, lots of processes have to be preset to react to various signals. However, when well-characterized modules are combined to construct higher order systems, unpredictable behaviors often occur because of the interplay between modules. Another significant problem is that complex integrated systems composed of numerous parts may cause cell overload.

    Figure 1. Schematic demonstration of HIV

    We proposed an elegant method to design higher order systems. Instead of merely combining different functional modules, we constructed one integrated processing module with fewer parts by utilizing the common structures between modules. The circuit we designed is a rewirable one and the topological structure of the processing module can be altered to adapt to environmental change. The basic idea is to rewire the connections between parts and devices to implement multiple functions with the help of the site-specific recombination systems.

    Our design approach may lead to a revolutionary step towards system integration in synthetic biology. Potential fields of application include organism development, living therapeutics and environment improvement.
