The Cell Cycle

Ke'Ron Blankumsee and Will Teepe

Interphase

G1 Phase

https://slideplayer.com/slide/6821425/23/images/17/G1+PHASE.jpg

G1 Phase

-During The G1 phase, the cell increases in size and makes new proteins and organelles

-G1 is like the warmup for the actual cell division

S Phase

S Phase

-In the S Phase, chromosomes are replicated and the synthesis of DNA molecules takes place ,

- Once a cell enters the S phase, it usually finishes the cycle

G2 Phase

G2 Phase

-In the G2 phase, many of the organelles and molecules required for cell

division are produced

-This phase is the shortest phase out of the others in interphase

-Once G2 is finished, the cell is ready to enter the M phase, called Mitosis

Mitosis

Mitosis

Prophase

Prophase

-During Prophase, the chromatin condenses into chromosomes and the centrioles separate

-The Nuclear envelope breaks down while the spindle begins to form

Metaphase

Metaphase

-In Metaphase, the second phase in mitosis, the chromosomes line up across the center of the cell.

-Each chromosome is connected to a spindle fiber at its centromere

-The centromere is the middle part of a chromosome, where the chromatids are connected

Anaphase

Anaphase

-In Anaphase, the 3rd stage in mitosis, the centromeres that join chromatids split, allowing the chromatids to separate and become their own separate chromosomes

-The chromosomes keep moving until they become two separate groups, one in each pole of the spindle

-Anaphase is over when the chromasomes stop moving

In Telophase, the chromasomes begin to disperse into a tangle of dense material. The spindle breaks apart and new nucleous becomes visible

Cytokenisis

Cytokenisis

Cytokenisis

Cytokenisis

-In cytokenisis, the cytoplasm of the cell splits up to create two cells, each with 23 pairs of chromasomes

-During cytokenisis in an animal cell, the cell membrane is drawn inward until the cytoplasm is pinched into two almost identical parts

-During cytoplasm in a plant cell, a structure called the cell plate forms midway between the divided nuclei.

-The cell plate slowly develops into a membrane, which eventually becomes the cell wall.

Final Result of Cell Cycle

Result

Once two separate cells are created, they are now ready to preform the cell cycle again, starting at interphase and working through mitosis and cytokenisis to be split up again
