The correct answer is: Centromere
- Centromere is the constricted portion of a chromosome
- Sister chromatids formed during cell division are attached to one another at centromere
- During cell division, the spindle fibers attach to the centromere and contract causing the sister chromatids to separate
- Based on the position of centromere, the chromosomes can be divided into metacentric, acrocentric, submetacentric and telocentric
- The part attached to the centromere are called the arm(s) of a chromosome
