Fig. 3: Analysis of edge categories in the E. coli TRN.

a Representation of the chromosomally embedded E. coli TRN. As in Fig. 1 the large light blue circle represents the circular chromosome and the blue line indicates the Ori–Ter axis. Black dashes on the chromosome indicate genes. b Edge categories for the chromosomally embedded E. coli TRN from a as a function of the axis position. The true Ori and Ter positions are indicated as a reference.
