Mitosis

Prophase

  • Two pairs of centrioles move to opposite poles (animals only)

  • Astral rays form around centrioles

  • Chromatin condenses - chromosomes become visible

  • Nucleolus disappears

  • Mitotic spindle forms

  • Spindle fibres begin to move towards centromeres

  • Chromosomes migrate to center of cell

Metaphase

  • Chromosomes line up at the equator of the cell.

  • Spindle fibres attach onto the chromosomes

Anaphase

  • Chromatids separate

  • Spindle fibres shorten - chromosomes are pulled towards poles.

Telophase

  • Interphase conditions

  • Nucleolus reopens

  • Spindle and aster disappear

Cytokinesis

  • Begins during telophase

  • Other parts of cells replicate

Plant Cell Mitosis

  • No centrioles

  • No astral rays
