The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests. Share: Facebook Twitter Pinterest LinkedIN Email.

During mitosis, centromeres serve as assembly sites for complex protein structures called kinetochores, which connect chromosomes to the spindle apparatus to appropriately distribute genetic ...

Cambridge, Mass. - April 26, 2012 - The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according ...

During cell division, the motor protein kinesin-5 hastens or retards microtubule sliding in the mitotic spindle, imparting forces that scale with the degree of microtubule overlap.

Around the spindle's center, they mostly exist in an anti-parallel configuration, ... the dynamic spindle apparatus out of purified proteins," says Kapoor, the senior author.

In order for this to happen correctly, the fibres of the spindle apparatus need to link to the chromosomes at the correct position. Here kinetochores come into play.

In research published October 1 in Developmental Cell, scientists at The Rockefeller University reveal new insights into the mechanical forces that govern elements of the mitotic spindle formation ...

The findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures. Organisms are composed of a variety of structures including muscles, ...
