研究了一个由相互催化分子组成的原始细胞模型，以研究在复制错误下化学成分如何通过细胞分裂递归传递。根据分子和物种的数量，以及路径速率，发现三个阶段：快速切换状态没有递归的生产，递归的生产，和以上两个状态之间的巡回。递归状态的分子的数量分布是对数正态的，除了那些物种，形成一个核心超循环，并解释了一个启发式的参数的帮助。
A protocell model consisting of mutually catalyzing molecules is studied, in order to investigate how chemical compositions are transferred recursively through cell divisions under replication errors. Depending on the numbers of molecules and species, and the path rate, three phases are found: fast switching state without recursive production, recursive production, and itinerancy between the above two states. The number distributions of the molecules in the recursive states are shown to be log-normal except for those species that form a core hypercycle, and are explained with the help of a heuristic argument.
