Nature connects {multiple|numerous|several|a number of|many|various} fuel-driven chemical/enzymatic reaction networks (CRNs/ERNs) {via|by way of|through|by means of} cross-regulation to hierarchically {control|manage|handle} biofunctions {for a|to get a|for any} tailored adaption in {complex|complicated} sensory landscapes. In contrast, emerging artificial fuel-driven systems most-ly {focus|concentrate} on a single CRN and their implementation to direct self-assembly or material responses. {In this|Within this} {work|function|perform|operate}, we introduce a facile {example|instance} of communication and cross-regulation {among|amongst} {multiple|numerous|several|a number of|many|various} DNA-based ERNs regulated by a concatenated RNA transcription regulator. For this {purpose|objective|goal}, we run two fuel-driven DNA-based ERNs by concurrent NAD+-fueled ligation and restriction {via|by way of|through|by means of} endo-nucleases (REases) in parallel.
