It is essential to explain the emergence of primitive cellular structure from a set of chemical reactions to unveil the origin of life and to experimentally synthesize protocells. Recently, we considered a hypercycle with two mutually-catalyzing chemicals to demonstrate that the reproduction of a protocell with a growth-division process occurs when the replication and degradation speeds of one chemical are slower than those of the other chemical respectively, and molecules are crowded as a result of replication. In this paper, we discuss the effects of the crowding molecule on the formation of primitive structure by simulating a cellular automaton model, and also apply the model to a hypercycle with three molecular species.
