What is the purpose of kinetochores?

Step-by-step solution

The kinetochores are the site where microtubules attach to the chromosomes, pulling the chromosomes towards opposite poles of the cell during mitosis. Small disc-shaped structures at the surface of the centromeres are called kinetochores. These structures serve as the sites of attachment of spindle fibres (formed by the spindle fibres) to the chromosomes that are moved into position at the centre of the cell. Hence, the metaphase is characterised by all the chromosomes coming to lie at the equator with one chromati
