A cell determines whether to undergo division at what are called checkpoints in the cell cycle. The activity of genes required to undergo the next stage in cell cycle is checked at these checkpoints by factors called cyclins and are aided by Cyclin-dependent kinases (Cdks), a type of enzymes.

∙ 12y agoFirstly, I want to correct the question, "How do cells divide".
Cells divide by two means;
- mitosis (diploid) in humans leads to replication and division of the entire cell including genetic matter - 46 chromosomes
- meoisis (haploid) in human leads to the division of the cell, with each cell conserving only half the genetic matter - 23 chromosomes * in sexual cells - sperm and egg
The actual cellular mechanism involves the replication of the genetic matter, followed by the up regulated growth of cellular structures such as centrioles. Once genetic material has been replicated, spindles are formed and the genetic material is quite literally pulled apart to opposite sides of the cell. Together with the increased cellular structures, two new daughter cells are formed, each consisting of 46 (in human) chromosomes
The process by which these cells receive the stimulus to divide are varied. They can include physiological as well as pathological stimuli;
- healthy growth factors - as part of general homeostatic body mechanisms, growth and development
- aberrant growth factors - resulting from cancers and disruption of protein kinase pathways as well as other growth regulatory mechanisms

Cells that retain the ability to divide continuously without specializing are called?
Stem cells are cells that are able to divide continuously without specializing. These kind of cells are undifferentiated biological cells.
When cells divide continuously and out of control?
Medical Science desperately Rushes In.
Do your Cells grow as you grow?
yes, cells grow to an enlarged size and divide into two small cells (which each enlarge and divide as well). but the larger cells get, the more difficult it is for them to function and operate, so they remain within certain size boundaries, getting large enough to divide and halving, large enough to divide and halving.
Why do cells need to divide?
One of the major aspects of life is self replication, or reproduction. If cells didn't divide, then populations of organisms would not form, and evolution would be impossible. The more proximate cause is that as cells grow and ingest food, there is a limit to how big they can become before the cell wall no longer supports the cytoplasm. At or before this point, the cell must divide or it will lyse (split open) and die.
What color are the blood cells when they carry oxygen?
the answer is that i dont know
When we grow do our cells grow or divide?
Cells divide.
Do skin cells divide?
yes. all skin cells divide and divide and divide all over your body.
How do the chromosomes divide between the new cells?
i dont know.. Ask someone who knows!
Do endothelial cells divide?
Yes, endothelial cells divide. It is important that these cells divide to replace old/dead cells and to create new blood vessels.
Do adult skin cells divide?
yes. all skin cells divide and divide and divide all over your body.
is a reason cells divide?
The cells divide into two daughter cells, to make way for replication.
Why do divide?
There are numerous reasons why cells divide. If someone skins their leg, for example, cells will divide for the purpose of replacing cells that have been damaged.
Why do somatic cells divide?
Somatic cells divide in order for organisms to grow and replace the cells that die.
Is it important for cells to divide?
If cells do not divide properly, then many problems can occur, cancer cells for example.
What is it called with the cell divide to create new cells is called?
It is called mitosis when regular cells divide. It is called meiosis when sex cells divide.
Why do larger cells divide?
all cells divide cells divide as a way to reproduce, the same way humans have babies and fish lay eggs.
What is reason cells divide?
The reason cells divide is because that helps you heal and grow
