👉 Kinetochore is a term used in cell biology to describe the region of the nucleus that is responsible for organizing and directing the movement of chromosomes during the cell cycle. In other words, it refers to the area where the DNA is copied from one strand to the other, which is essential for the proper functioning of the cell. Kinetochore is located at the center of the cell, near the centromere, and extends up to about 50 micrometers in length.
