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.
There are five main steps of mitosis. 1  Prophase: the nuclear envelope breaks down, chromosomes condense, and spindle fibers connect to sister chromatids. 2  Metaphase: spindle fibers pull sister chromatids to the metaphase plate at the equator of the cell. 3  Anaphase: spindle fibers separate sister chromatids to opposite poles of the cell.
