Cells divide by 'bricklaying on moving scaffolding'

(Delft University of Technology) Researchers have succeeded in finding out how bacteria cut themselves into two daughter cells. The bacteria appear to build a new cell wall working from the outside in with the help of multiple molecular 'bricklayers'. The 'bricklayers' move along the inside of the wall under construction by 'treadmilling'; the building of the cell wall is performed from scaffolding that is continuously being moved at the front, while at the rear it is continuously being dismantl...
