How cells get to be the right size and put things at the right place inside them

Abstract
In this talk I will discuss how fission yeast cells control their size, a fundamental question in cell biology. I will propose a theory that explains how this can be performed via an effective measurement of the plasma membrane surface area. Predictions from this theory are then successfully tested in the lab. I will then more briefly discuss a second problem, how low copy number plasmids in bacteria are equally spaced throughout the cell, thereby leading to equal partitioning at cell division. Surprisingly the mechanism at work here may be related to the phenomenon of cell size control. Throughout the talk I will illustrate how highly quantitative approaches can help to accelerate the discovery of fundamental biological mechanism.
