Explanation:

Duplicated centrioles are responsible for moving chromosomes during mitosis.

They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.

It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.

Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.

They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.

Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.

These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.

During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.

At the end in telophase, where nuclear membrane becomes visible it disappears.

In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.
