We will study plausible geological non-equilibrium environments composed of open rock pores for their suitability to continuously supply biochemical reaction networks driving replication and expression of genetic information. The aim is to host and position these complex reaction networks over an extended period of time through physical disequilibria without the need for membranes, while maintaining their activity. We will use recombinant in vitro translation systems coupled to DNA replication and energy regeneration as a proxy for a metabolic system capable of maintaining both flow of genetic information as well as a minimal metabolism.

我们将研究由开放岩石孔隙组成的合理地质非平衡环境，以了解它们是否适合持续提供驱动遗传信息复制和表达的生化反应网络。其目的是通过物理不平衡在较长时间内托管和定位这些复杂的反应网络，而不需要膜，同时保持其活性。我们将使用与 DNA 复制和能量再生相结合的重组体外翻译系统作为代谢系统的代理，该系统能够维持遗传信息流以及最低限度的新陈代谢。
