hey mate this is your answer,

A kinetochore is a protein structure that forms on a chromatid during cell division and allows it to attach to a spindle fiber on a chromosome.

The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored during cell division of mitosis and meiosis.

The centromere is the primary constriction of a chromosome. In the following diagram, you can see that the centromere region is pinched in.

Kinetochores are two discs of proteins, located at the centromere, on opposite sides of the chromosome. The microtubules that attach to the chromosomes actually attach to the kinetochores (which is why those microtubules are called kientochore microtubules).
