Modeling Mitosis

BEFORE: Interphase

Interphase is simply the resting phase of the cell.

STAGE 1: Prophase

Prophase is the first stage of mitosis – during prophase, the nuclear envelope dissolves/disappears, as well as chromosomes becoming visible as paired chromatids.

———————————————–

STAGE 2: Prometaphase

Prometaphase falls between prophase and metaphase… it is the stage of eukaryotic division. In this stage, the chromosomes condense, and the cell’s centrosome divides, moving to opposite sides of the cell.

STAGE 3: Metaphase

Metaphase – M for middle ! Metaphase is the stage during which the chromosomes attach to the spindle fibre’s and line up in the middle.

———————————————–

STAGE 4: Anaphase

Anaphase – A for away! Anaphase is the stage in which chromosome’s disperse and move away from each other to opposite poles of the spindle fibre’s.

STAGE 5: Telophase

Telophase is the stage of cell division where chromatids or chromosomes move to opposite ends of the cell. After that’s done, two nuclei are formed.

STAGE 6: Cytokinesis

Cytokinesis is the end of the cell division cycle. During it, the cell splits into two daughter cells.
