Question

What is the relationship between chromosomes spindle fibers and centromeres

Answer 1

SPINDLE FIBERS

In Mitosis, Spindle Fibres form at opposite poles of the cell and meet at the equator. Collectively, they form a spindle-shaped structure which attach to Centromeres.

CENTROSOMES

The organelle located near the nucleus in the cytoplasm,
composed of 2 centrioles that divides during S Phase

Centrioles are surrounded by a mass of proteins (Pericentriolar Material (PCM))

Migrates to opposite poles of the cell during mitosis

Involved in the creation of spindle fibres

CHROMOSOMES

A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Centromeres
The constricted region joining the two sister chromatids that make up an X-shaped chromosome. It also serves as the point of attachment for spindle fibers when the spindle fibers are pulling the chromosomes toward the centrioles (situated on opposite poles in a cell) prior to cytokinesis.
