A Correct answer
Explanation

The kinetochore is the protein structure on chromatids, where the spindle fibers attach during cell division to pull sister chromatids apart. The kinetochore forms in eukaryotes, assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.
