Interphase
• Time when a cell is not dividing
• G
1
• (G
0
– Gap 1 – Growth
– Gap 0 – resting, leaves cell cycle)
• S – synthesis; DNA replication
• G
2
– Gap 2 - prepares for cell division (replicates organelles), makes sure cell is ready for mitosis

Mitosis - Prophase
• First stage of mitosis
• Chromosomes are visible
(condensed)
• Centrioles separate (to the poles)
• Spindle fibers expand from centrioles (mitotic spindle)
• Nuclear membrane breaks down
• Nucleolus breaks down

Mitosis - Prophase
• First stage of mitosis
• Chromosomes are visible
(condensed)
• Centrioles separate (to the poles)
• Spindle fibers expand from centrioles (mitotic spindle)
• Nuclear membrane breaks down
• Nucleolus breaks down

Mitosis - Metaphase
• Shortest phase
• Chromosomes line up in the middle of the cell
• Spindle fibers attach to the centromeres (point of attachment called kinetochore)

Mitosis - Metaphase
• Shortest phase
• Chromosomes line up in the middle of the cell
• Spindle fibers attach to the centromeres (point of attachment called kinetochore)

Mitosis - Anaphase
• Sister chromatids separated
• Pulled to opposite poles by spindle fibers

Mitosis - Anaphase
• Sister chromatids separated
• Pulled to opposite poles by spindle fibers

Mitosis - Telophase
• Final stage
• Chromosomes become indistinct (back to chromatin)
• Nuclear envelope reforms
• Each nucleus: 2n, identical
• Mitosis is complete, cell division is not
• Cytokinesis occurs, cytoplasm divides

Mitosis - Telophase
• Final stage
• Chromosomes become indistinct (back to chromatin)
• Nuclear envelope reforms
• Each nucleus: 2n, identical
• Mitosis is complete, cell division is not
• Cytokinesis occurs, cytoplasm divides

Interphase
• Results in two identical cells
• Cycle continues as both cells enter interphase
