Cell division: Burning the spindle at both ends
Rebecca W. Heald1
Abstract
Accurate transmission of the genome during cell division requires the physical separation of replicated chromosomes. The identities of two molecular motors needed to do the job in fruitflies are now revealed.
A dramatic event in the life of a cell is its transformation into two genetically identical progeny. This is achieved during mitosis, when an exact complement of chromosomes is partitioned to each half of the cell, just before it pinches into two1.
