How chromosomes meet in the dark

A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development. Their discovery could also provide new insights into how other similar chromosomes spontaneously recognise each other and are bound together at key parts of analogous cell processes. This is an important mechanism as the binding together of too many of too few of a particular chromosome can cause a number of medical conditions such as Down's Syndrome or Turner's Syndrome...
