Cell division is essential to the propagation of life. During cell division, mitotic spindles segregate duplicated chromosomes with high fidelity. Spindle structure depends on the proper polar ...

A large structure called the mitotic spindle also forms from long proteins called microtubules on each side, or pole, of the cell. During prometaphase, the nuclear envelope that encloses the ...

The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers ...
