Question

Quizplus · Accepted Answer

Sister chromatids are joined at the centromere, a specialized region on the chromosome. During cell division, the spindle fibers attach to the centromere and pull the sister chromatids apart, ensuring that each new daughter cell receives an exact copy of the original chromosome. The centrosome and centriole are important organelles involved in the formation of the spindle, but they do not directly attach to the sister chromatids.
