Fig. 4From: From molecular to cellular form: modeling the first major transition during the arising of lifeThe spread of NSR in the system with REP thriving. Based upon the case of Figs. 2, 50 NSR molecules with a sequence of “CSTag + CSNSR + CSTag” (see Methods for explanation) are inoculated at step 2 × 106 (see arrow) into the system (distributed in 10 randomly chosen grid rooms containing REP, five each)Back to article page
