In this diagram o a duplicatit chromosome, (2) identifies the centromere—the region that jyns the twa sister chromatids, or each hauf o the chromosome. In prophase o mitosis, specialised regions on centromeres cried kinetochores attach chromosomes tae spindle fibers.

The centromere (centro- + -mere) is the pairt o a chromosome that airts sister chromatids. During mitosis, spindle feebres attach tae the centromere via the kinetochore.[1]
