How the Mitotic Spindle Guides Cell Division

The mitotic spindle guides chromosome movement during cell division. It is a structure made of microtubules, which are thin protein fibers in the cell. These fibers organize and help separate the genetic material before the cell splits.

The spindle forms as the cell prepares to divide. Its fibers...

The mitotic spindle separates sister chromatids and moves them to opposite sides of the cell during anaphase of mitosis.

Fundamental structures of the mitotic spindle are hollow cylinders called microtubules. Two sets of microtubules are arranged on opposite ends, or poles, of the mitotic spindle.

Each microtubule has a minus end a...
