Our latest work is out in PNAS!🎉
We show that nonequilibrium polysome dynamics help drive sister chromosomes apart. The closing division septum also contributes via steric interactions.👇

Diagram of an E. coli cell showing polysomes pushing sister chromosomes apart. Bottom heatmaps show cell-cycle-dependent changes in DNA and ribosome density distributions, and constriction formation. The top right corner shows normalized mid cell amounts from these heatmaps (integrated between the dashed horizontal lines).
