Q.

What is the main function of the spindle fibers during mitosis?

  1. A

    To regulate cell growth

  2. B

    To separate the chromosomes

  3. C

    To synthesize new DNA

  4. D

    To repair damaged DNA

Solution

Spindle fibres are microtubules that attach to the kinetochores at the centromere of each chromosome during mitosis. By shortening, they pull sister chromatids apart toward opposite poles of the cell, thereby separating the chromosomes equally into the two daughter cells.
