What is a cell cycle stop?
Cell cycle stop is a stop point in the cell cycle, where it is no longer involved in processes surrounding duplication and division. The natural cell cycle contains a number of checkpoints that allow the cells to determine whether it will continue to divide or stop. These stops can also be caused by external factors such as exposure to radiation or drugs used to control cell growth. Research on the cell cycle stop providing important information about how cells are regulated and what happens when these processes go wrong. During the phase with actively copy its genetic material called deoxyribonucleic acid (DNA) and in G2 has the opportunity to repair damage before m, mitosis. After mitosis, cells can re -enter G1 or go to G0 where they rest. In each of these stages, the checkpoint temporarily stops the cell cycle to decide whether to continue. Some cells are programmed to duplicate rarely, while damaged cells may need time to repair or destruction.
Sometimes the cell cycle stops with apoptosis, cell death. This happens when the cell feels that it is no longer functional due to DNA damage. The cell focuses on destruction and closes, allowing the body to clean the detritus and reuse it in the production of other cells. Cell cycle stopping allows cells to maintain their integrity by stopping to regularly check signs of DNA destruction, which could cause functional problems or lead to tumor development. It is not always a perfect process, as shown in the development of cancer growth.
drugs can be able to introduce a cell cycle, either by chance or as part of their therapeutic properties. Cells in culture can respond to these drugs by stopping the divorce of ISION, illustrating that something in the healing causes the cells to hit the checkpoint and remain there. These drugs can be used for activities such as Cancer TherapyNY, where the goal can be to prevent continued replication of tumor cells to reduce cancer growth. In other cases, the temporary stop is a random and unintended side effect.
Environmental factors can also play a role in the arrest of the cellular cycle. Some unicellular organisms have the ability to enter a state of suspended animation in response to unfavorable conditions and revival when the environment is more friendly. In some conditions, specific multi-cell organisms are also capable. Exposure to high levels of radiation or chemicals can also cause a cell cycle to stop in some organisms.
