How cells control nuclear size becomes clearer

(Hiroshima University) Over a century since scientists first observed that cells and their nucleus grow at a constant ratio, we are now closer to finding out how.This study was carried out by Assistant Professor Kazunori Kume of Hiroshima University and supervised by Nobel Laureate Sir Paul Nurse.It discovered that hoarding of genetic materials (mRNA) and proteins by the nucleus causes it to bulk up and is enabled by the amount of nuclear membrane supplied.
