Now, the number of centromeres and chromosomes within the cell is doubled. Note that each separated chromosome has only one chromatid ... WebThe main function of a centromere is joining the sister chromatids. 4) Sister chromatids: Sister chromatids are the two identical halves of a single replicated eukaryotic chromosome.
