Vedclass · Answer

(A) The centromere is a specialized $DNA$ sequence of a chromosome that links a pair of sister chromatids. During cell division,the kinetochore,which is a protein complex,assembles on the centromere. Spindle fibers attach to these kinetochores to pull the sister chromatids towards opposite poles during anaphase. Therefore,the centromere is essential for the movement of chromosomes towards the poles.
