Presidents, Vice Presidents, and Death: Closing the Constitution's Succession Gap

Some Thoughts on the Electoral College: Past, Present, and Future

We review several lines of evidence, arguing for a shared evolutionary past of the divisome and elongasome. Both integrate closely related penicillin-binding proteins (PBPs) for PG synthesis, use proteins of the RodA/FtsW (SEDS, shape, elong...
