The cell cycle is divided up into separate phases (S, G0, G1, M); each point of transition from one phase to another (a checkpoint) is governed by multiple proteins which serve as either "accelerators" or "brakes" for the cell cycle. These proteins are coded by chromosomes (DNA), and it is the mutation in the protein-specific DNA which creates either no protein, overactive protein, or underactive protein. IN any case, it creates a disruption to the cycle, which disturbs orderly cell growth and division. This can lead to cancer.
This is known as the cell cycle.
If cell division were not controlled, there would be unrestricted over growth of cells to form a shapeless mass of cells called a tumor. Uncontrolled cell growth is called cancer
It is unlikely for a cell in the G0 Phase to become a tumor cell, because cells do not divide in the G0 Phase.
THE CELL CYCLE.
Cell Cycle
When the cell cycle become uncontrolled, a tumor can form.
The growth of a cancerous tumor
This is known as the cell cycle.
formation of a cell plate
The formation of a tumor, which may or may not be cancerous.
formation of a cell plate
the frowth fraction is •The proportion of cells in a tumor population that are actively proliferating.
The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
Ff a cell is uncontrolled means it will divide vigourously in abnormal manner and will cause tumor of cancer.
The region of the viral genome (DNA in DNA tumor-viruses or RNA in RNA-tumor viruses) that can cause a tumor is called an oncogene. This foreign gene can be carried into a cell by the virus and cause the host cell to take on new properties such as immortalization and anchorage-independent growth.
