When a bacterial cell divides into two daughter cells there can be an uneven distribution of cellular organelles. The resulting cells can behave differently from each other, giving them an evolutionary advantage.
New research shows bacteria may draw other bacteria to an infection site by laying down trails of a “molecular glue” that attract free-swimming individual bacteria.
Bacteria speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Collisions can result in mutations.
