Question

What is the main function of spindle fibers?

A.) To condense chromatin into chromosomes.
B.) To replicate the chromosomes before cell division.
C.) To decondense chromosomes following mitosis.
D.) To separate chromosomes during mitosis.

Answer 1

The correct option is D. To separate chromosomes during mitosis.

Step-by-step explanation:

All cells of the body replicate through the process of mitosis except the sex cells. The formation of the spindle fibres is a very important step in the mechanism of mitosis and meiosis both.

Spindle fibres are present on the opposite poles and pull the chromosomes to each side. As a result, the chromosomes get separated into two halves and gametes are formed. This process also ensures that equal division takes place.
