Stages of Mitosis

Interphase

Contains G1, S, and G2 phases where regular cell function and metabolism continues

Interphase - G1 Phase

Cell’s organelles are doubled and the materials that will be utilized for DNA synthesis are produced

Interphase - S Phase

DNA replication

Interphase - G2 Phase

Proteins needed for cell division are synthesized and chromatids condense

Chromatids

Duplicated chromosomes

Centromere

Place of attachment for chromatids

Prophase

Nuclear membrane breakdown, mitotic spindle apparatus assembly, and spindle fibers attach to centromere and centrioles

Metaphase

Chromatids line up at metaphase plate in midline of cell

Anaphase

Centromeres divide and sister chromatids split, being pulled toward opposite poles

Telophase

Spindle apparatus disassembled and new nuclei form at poles

Cytokinesis

Parental cell splits into two identical daughter cells

Cleavage Furrow

Belt of actin filaments that constrict between new nuclei in cytokinesis
