How do cells assemble the mitotic spindle and ensure correct chromosomal segregation?

0

Improper chromosomal segregation during cell division is an underlying cause of birth defects and may participate in the etiology of certain cancers. Understanding how the mitotic spindle assembles and partitions chromosomes is, therefore, a fundamental goal of cell biology that also has a significant impact on human health. The lab is using Drosophila cells as a system in which to identify molecules that are essential for the faithful segregation of chromosomes.
