The very modular concept behind BIOMODULEs an BioBrick® is the same. A BIOMODULE is a standard biological part with a well-defined DNA sequence. BIOMODULEs are the building blocks of DOULIX platform and allows you design large and complex synthetic biological constructs by assembling small and well-characterized DNA parts. The main advantage is modularity concept behind BIOMODULEs, indeed any BIOMODULE can be reused in different constructs to streamline and speed-up the design process.
