What happens when cell is not dividing? |
The chromosomes creates a chromatin network |
|
|
|
What happens when cells are dividing? |
The chromatin network condenses and becomes shorter and thicker and the chromosomes are visible |
|
|
|
Explain replication |
It's when the DNA in the chromosomes have to duplicate itself before the cell can divide. |

What is cancer |
Cancer is the uncontrolled mitotic cell division which leads to a growth of an abnormal tissue. |
|
|

|
Explain the cancerous tumor. |
Malignant-it spreads between the cells of the tissues and when cell spread by the circulation of blood. This is when they start to metastasis. And it does not have a capsule. |
|
|
|
Metastasis |
It's when cancerous cells spread by the circulation of blood and new tumors form in other parts of the body |
