Interphase-------> G1, S, G2

G1--->G=GROW!     

Cell grows rapidly             

while carrying out                 

routine functions

 S=Synthesis Phase

  DNA replication occurs 

  in S phase. Synthesis=to make

G2 - 2nd growth phase

G2= Double check for errors!

Errors in DNA replication are checked and fixed.

DNA REPLICATION:

It occurs in the S phase which is Synthesis Phase. 

DNA replication means our cells make a copy of our DNA before it divides. 

We need 2 copies - one for each cell

is the biological process of producing two identical replicas of DNA from one original DNA molecule.

MITOSIS:

PLEASE MAKE ANOTHER TWO CELLS
Mitosis is the division of the nucleus

4 phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase

Prophase= Prepare

Cell is preparing to divide!
Metaphase=Middle

Chromosomes move to the middle!

Anaphase=Apart

Chromosomes are pulled apart!

Telophase=Two

Two nuclei start to form.

CYTOKINESIS is the division of the cytoplasm

After mitosis, cytokinesis occurs (dividing the cytoplasm) between the 2 identical daughter cells, completing the cell division.

Cytokinesis= CHOP!

Division of the cytoplasm by CHOPPING it in half!

CANCER:

When the control of the cell cycle is lost, or there is a mistake along the way, the result is cancer.

Cancer is uncontrolled cell growth.

Stuff that cause cancer are: 

Cigarette smoke, UV radiation from sun, Carcinogens, Air and Water pollution and Viral Infection.

Tumors are created by cancerous cells affecting normal cells.
