What is an example of proliferation?
Proliferation is a rapid increase in numbers or rapid growth. When a country is quickly building up more weapons including nuclear weapons, this is an example of nuclear proliferation. If you start out with one rabbit and within a month you end up with five, this is an example of proliferation of rabbits.
What is proliferation in biology?
Cell proliferation is the process that results in an increase of the number of cells, and is defined by the balance between cell divisions and cell loss through cell death or differentiation.
What does Proliferation mean in medical terms?
Proliferation is the growth of tissue cells. In many diseases, it is abnormal. They have high rates of cell division and growth.
What is the meaning of Plorification?
Proliferation is a rapid multiplication of parts or the increase in the number of something. Nuclear proliferation is a rapid increase of nuclear weapons. The proliferation of any living thing will often create an overpopulation problem and cause an environmental imbalance.
What is another word for proliferation?

What does Proliferation mean in politics?
Proliferation describes growth by the rapid multiplication of parts. In its politico-military context, proliferation most commonly refers to nuclear weapons, and sometimes covers all weapons of mass destruction—biological, chemical, and radiological as well as nuclear.
What does proliferation of weapons mean?
Proliferation means growth or multiplication. U.S. goals for non-proliferation (or counterproliferation) include stopping the development of new weapons, reducing and safeguarding the stockpiles of existing weapons, and preventing the spread of WMD technology, particularly among enemies of the United States.
How do you use proliferation?
Proliferation sentence example
- It may also take place where rapid proliferation of the cell is going on, as in the budding of the Yeast plant.
- This phenomenon is known as proliferation of the floral axis.
What does excessive proliferation mean?
the growth or production of cells by multiplication of parts. a rapid and often excessive spread or increase: nuclear proliferation.
Is cell proliferation bad?
The process by which cells grow and divide to replenish lost cells is termed cell proliferation. This is a highly regulated activity in normal, healthy tissue.
What causes cell proliferation?
Normal cell proliferation occurs following a four-step cycle, known as the cell cycle: G1 phase, when cells grow and stock up on nutrients; S phase, when their DNA is duplicated; G2 phase, when DNA is checked for duplication errors and M phase, when the cell divides giving birth to two new cells.
What happens when there is too much cell proliferation?
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
What is abnormal cell proliferation?
A tumor is any abnormal proliferation of cells, which may be either benign or malignant. A benign tumor, such as a common skin wart, remains confined to its original location, neither invading surrounding normal tissue nor spreading to distant body sites.
What prevents cell proliferation?
Neighboring Cells Compete for Extracellular Signal Proteins At this point, normal cells, unlike cancer cells, stop proliferating—a phenomenon known as density-dependent inhibition of cell division.
What controls cell proliferation?
Although both cyclins and CKIs can be regulated at the level of mRNA stability, translational control, and subcellular localization, the two major control mechanisms are transcriptional regulation and ubiquitin-dependent proteolysis.
What is required for cell proliferation?
Cell proliferation is tightly controlled in normal cells, while cancer cells possess excessive cell proliferation due to sustaining proliferative signaling and evaded growth suppressors. Altered miRNA expression is a key determinant for excessive cell proliferation and tumorigenesis.
What process regulates proliferation?
Abstract. Cell proliferation is regulated by a coordinated entry into the cell cycle. This process is an obligated step during any remodeling or regeneration of tissues. Interestingly, most of the cell proliferation processes are accompanied by an adapted metabolic response.
What is the difference between cell growth and cell proliferation?
Cell growth refers to the increase in cell size (mass accumulation) while cell division describes the division of a mother cell into two daughter cells (1->2->4->8, etc.). Cell proliferation is the process of generating an increased number of cells through cell division.
Why is cell proliferation important?
To develop bodies and organs, cell proliferation of multiple rounds is necessary in all multi- cellular organisms during embryogenesis. In this way, regulation of cell proliferation is very important for development and also related biological areas, and the knowledge of underlying mechanisms is accumulating.
