The spindle apparatus of Coprinus micaceus begins to develop from the diglobular polar body outside the nucleus. During both meiotic divisions it operates inside the nuclear envelope and consists of ...

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of ...

Cell division is a fundamental process by which one cell generates a multicellular organism. Thereby, the genetic material gets distributed between two daughter cells by the spindle apparatus. The ...

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, ...

The spindle assembly checkpoint arrests mitotic progression until each kinetochore secures a stable attachment to the spindle. Despite fluctuating noise, this checkpoint remains robust and remarkably ...

Researchers have for the first time directly observed the “molecular motor”, called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. The study ...

The symmetrical arrangement of chromosomes and the mitotic spindle during metaphase creates an obvious point for initiating cell cleavage and ensures that the mother cell divides equally and ...

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests. The mitotic spindle, an apparatus that segregates ...
