    2. 2. <ul><li>DNA has replicated, but has not formed the condensed structure of chromosome. They remain as loosely coiled chromatin. </li></ul><ul><li>Nuclear membrane still intact to protect the DNA molecules from undergoing mutation. </li></ul>
    3. 3. <ul><li>The DNA molecules progressively shorten and condense by coiling, to form chromosomes. </li></ul><ul><li>The nuclear membrane and nucleolus are no longer visible </li></ul><ul><li>The spindle apparatus has migrate to opposite poles of the cell. </li></ul>
    4. 4. <ul><li>The spindle fibers attach themselves to the centromeres of the chromosomes The fibers align the chromosomes at the equatorial plate. </li></ul>
