Answer: When cell cycle is not controlled, it leads to still alive older cells and newly formed younger cells growing along with each other resulting in a tumor which is malignant, that is cancer. This can happen due to many factors as a result of genetic mutations.
Explanation:
A lack of control on cell cycle would cause older living cells to grow alongside younger living cells (newly formed), thereby, resulting in the formation of malignant cells (tumors) such as cancerous cells.
A cell cycle refers to an ordered sequence of events that takes place within a living cell as it grows and divide into two new daughter cells.
Basically, there are four (4) main stages in a cell cycle and these are:
The cell cycle is usually controlled and regulated so as to ensure living cells only divide as and when required by the body system of a living organism.
Hence, at each stage of a cell cycle, a set of conditions and control system determines whether or not a particular cell will continue into the next stage.
Generally, the cell cycle is controlled by cyclin-dependent protein kinases (Cdks) and regulated by subunits referred to as cyclins.
In conclusion, lack of control on cell cycle would cause older living cells to grow alongside younger living cells (newly formed), thereby, resulting in the formation of malignant cells (tumors) such as cancerous cells.
