During the metaphase stage of mitosis, spindle fibres attach to chromosomes at:

Step-by-step solution

During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane. Related Theory The centromere is a DNA region where they join sister chromatids together, whereas kinetochore is an assembling protein complex in the centromere where they attach to opposite poles of the mitotic spindle.
