Cell growth and progression through the cell cycle is a process that requires tight regulation. We have specific genes that can inhibit the progression of a cell through the cell cycle. If these genes are damaged through a mutation, what could be the consequence?

When there is a malfunction of the cell reproduction sequence regardless of the cause (whether it is damaged by mutation, internal or external disruption of the cell reproduction cycle or other factors, the most approximate result is Cancerous growth.

Explanation:

The genes which regulate cell growth can be likened to the brakes of a vehicle. The brakes ensure the car stops when it has to. This prevents accidents, damages, death and destruction of property.

When the mechanism for the replication and replacement of cells go out of control, all sorts of malformations emerge. We term them cancerous tissues.

Cheers!

Chemotherapy works by stopping or slowing the growth of cancer cells, which grow and divide quickly. It can also harm healthy cells that divide quickly, such as those that line your mouth and intestines or cause your hair to grow. Damage to healthy cells may cause side effects. Chemotherapy kills cells that are in the process of splitting into 2 new cells. Because cancer cells divide much more often than most normal cells, chemotherapy is much more likely to kill them. Some drugs kill dividing cells by damaging the part of the cell's control centre that makes it divide.

not till now just stay indoors and was hand frequently
