New models question old assumptions about how many molecules it takes to control cell division

A single cell - whether a yeast cell or one of your cells - is exquisitely sensitive to its surroundings. It receives input signals, processes the information, makes decisions, and issues commands for making the proper response. As with any control system, noise - errors, slip-ups, mis-reads - can get in the way of correct decision making. Virginia Tech biologists and engineers have created a mathematical model to explore the roles of noise in controlling the basic events of the cell cycle - DNA replication and cell division...
