Which of the following best describes the kinetochore? the array of vesicles that will form between two dividingnuclei and give rise to the metaphase plate a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules the centromere region of a metaphase chromosome at which the dna can bind with spindle proteins the core of proteins that forms the cell plate in a dividing plant cell the ring of actin microfilaments that will cause theappearance of the cleavage furrow

a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules

Explanation:

Kinetochores have  vvery important role in the cell division-mitosis.

During the metaphase of mitosis, spindle fibers attach to kinetochores. Some of the microtubules bind to kinetochore (kinetochore microtubules) while other don’t: they connect with the microtubules from the opposite pole, stabilizing the spindle.

During the anaphase, kinetochore microtubules pull chromosomes toward poles, helping the sister chromatids separate from each other.
