Fig. 7

The influence of molecular movement on the spread of REP. The case shown in black is the same as the one of Fig. 2. At step 3 × 106, the moving rate of molecules is changed, deriving the cases shown in other colors. a The changed rate is PMV, which determines the movements of all molecules. Note that the parasites recorded here and those shown in Fig. 8 appear de novo in the system, which have been traced by us and turn out to be the strongest parasites – i.e., the shortest ones able to be replicated continuously, with merely a sequence of “CSTag + CSTag”. b The changed moving rate is of raw materials (i.e., nucleotide precursors). c The changed moving rate is of ribozymes (i.e., REP). d The changed moving rate is of parasites (i.e., other RNAs with two end-CSTags)
