Interphase
Description : A period of growth in which a cell can spend 90% of its time. This part of the cycle is divided into three phases: G1, S, and G2.

Interphase
Chromatin is a mass of genetic material composed of DNA and proteins that eventually condenses to form chromosomes

G1 (Gap 1)
Description : A period of activity in which cells do most of their growing. Cells increase in size and synthesize new proteins and organelles.
The G1 checkpoint ensures that the cell is large enough to divide, and that enough nutrients are available to support the resulting daughter cells.

S (Synthesis)
Description : Synthesis of DNA molecules takes place as chromosomes are replicated. Key proteins are also synthesized.

G2 (Gap 2)
Description: Many organelles and molecules required for cell division are produced here. Once this phase is complete, the cell is ready for mitosis.
The G2 checkpoint ensures that DNA replication in S phase has been completed successfully.

Prophase
Description:
The chromatin condenses into chromosomes.
The centrioles (in animals) separate, and a spindle begins to form.
The nuclear envelope
breaks down.
Longest phase of mitosis.

Metaphase
Description:
The chromosomes line up across the center of the cell.
Each chromosome is connected to a spindle fiber at its centromere.
Metaphase checkpoint ensures that all of the chromosomes are attached to the mitotic spindle by a kinetochore .

Phase Identification
Look at the onion root tip cells in your booklet and see
how many cells you can find in each stage.
Chose a color for each stage and outline the cell in that
color.

G0 (G zero)
If the cell does not receive a signal to “go ahead” at the G1 checkpoint it will not go into the dividing phases (Mitosis)
The cell is now said to be in G0
Most cells in your body are in this stage.

G0 (G zero)
Examples of cells in G0
Nerve cells
muscle cells
Liver cells (although these cells can be “called back” into the dividing phases of mitosis based on external cues such as growth factors)

Cancer
Cancer is a disorder in which some of the body’s own cells lose the ability to control growth.
Cancer cells do not respond to the signals that regulate the growth of most cells (G1 checkpoint is bypassed).
As a result, they divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues.
