Cell biology: The checkpoint brake relieved
Jan-Michael Peters1
Abstract
When a cell divides, each daughter cell inherits a complete set of chromosomes. A sophisticated inhibitory mechanism delays chromosome segregation and cell division until everything is in its place.
It is equally important for a cell to do things at the right times as it is for an organism. This is particularly true during the final phase of cell division — mitosis — when chromosomes segregate.
- Jan-Michael Peters is at the Research Institute of Molecular Pathology (IMP), Dr. Bohr-Gasse 7, A-1030 Vienna, Austria.
