Which best describes the kinetochore? A structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules. The array of vesicles that will form between two dividing nuclei and give rise to the metaphase plate. The ring of actin microfilaments that will cause the appearance of the cleavage furrow. The centromere region of a metaphase chromosome where the DNA can bind with spindle proteins.
