Model comparison with experimental GFP shuffling. The length distribution of reassembly reactions in lanes A, C, G, and I in Fig. 2 are plotted, corresponding to four shuffling conditions: low (8 ng/μl) or high (120 ng/μl) concentrations and larger (AFS, 50 bp; MFS, 50 bp) or smaller (AFS, 45 bp; MFS, 25 bp) fragment sizes. Simulated curves based on these conditions for 14 theoretical shuffling rounds are plotted for comparison.
