What cellular component helps pull the chromosomes apart in mitosis and meiosis? The cellular component that helps pull apart the chromosome in mitosis and meiosis are the spindle fibers. These spindle fibers are made of micro-tubules.
During metaphase of mitosis, chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres. During anaphase of mitosis, paired centromeres in each distinct chromosome begin to move apart as daughter chromosomes migrate centromere first toward opposite ends of the cell.
