Cell Cycle Mitosis & Cytokinesis

Cell Cycle The regular sequence of growth and division that cells undergo is known as the cell cycle. During the cell cycle, a cell grows, prepares for division and divides into two new cells (called daughter cells)

Interphase A nondividing cell Cell grows to its mature size, makes a copy of its DNA (genetic code) Prepares to divide into two cells Two cylindrical structures called centrioles are also copied. Centrioles DNA is copied in the nucleus

Cells in Interphase (not dividing)

Prophase 1st stage of Mitosis (dividing of nucleus) Centriole 1st stage of Mitosis (dividing of nucleus) Chromatin in the nucleus condenses to form chromosomes Pairs of centrioles move to opposite sides of the nucleus Spindle fibers form a bridge between the ends of the cell The nuclear envelope breaks down Spindle Fiber Apparatus

Chromatids: Two identical chromosomes Centromere joins the chromatids

Early Prophase Late Prophase

Metaphase 2nd stage of Mitosis The chromosomes line up in the middle of the cell. Each chromosome attaches to the spindle fiber at its centromere.

Spindle Fiber Apparatus Metaphase

Anaphase 3rd Stage of Mitosis The centromeres split The two chromatids separate, and each chromatid becomes a new chromosome. The new chromosomes move to opposite ends of the cell. The cell stretches out as the opposite ends are pushed apart.

Anaphase

Telophase 4th stage of Mitosis The chromosomes begin to stretch out and lose their rod like appearance. A new nuclear envelope forms around each region of chromosomes.

Telophase

Cytokinesis Cell membrane pinches around the middle of the cell The cell splits in two Each daughter cell ends up with an identical set of chromosomes and about half the organelles.
