Cells go through a cycle that has several distinct stages, called
M (for mitosis), G1 (first Gap or Growth stage), S (for DNA synthesis)
and G2 (second gap). The decision to divide is made during G1 stage,
when the cell "senses" that its growth conditions or status is OK to
divide. The real signal is not entirely clear yet; there are probably
several such signals that get integrated together to make the decision.
We are learning a lot about the machinery that then gets things moving;
I can supply more details if you wish. Once the decision in G1 is made
the rest of the cell cycle proceeds more or less like clockwork; 6-8 hours
for DNA synthesis, a few hours in G2 (to get ready to divide), and an
hour or so in Mitosis itself. Totally not mine, just trying to help.
Three sources of signals related to the regulation of cell growth and division are growth factors, hormone signals, and signals from neighboring cells. Growth factors are molecules released by cells that promote cell proliferation. Hormone signals, such as those from the reproductive system, can also influence cell growth and division. Signals from neighboring cells, called contact inhibition, can regulate cell growth by preventing cells from dividing when they come into contact with other cells.
Somatic cells or body cells perform mitosis.
Somatic cells undergo mitosis.
Mitosis occurs in Eukaryote cells. An example of a cell that would undergo mitosis would be an injured skin cell. Don't get mitosis confused with meiosis, however. Mitosis is non-sexual reproduction, while Meiosis is sexual.
Hi, Mitosis produces gametes that are sex cells. Mitosis produces 2 identical cells.

Mitosis occurs in somatic cells. The main purpose of mitosis is to create two identical cells from one single cell.
Mitosis occurs in somatic cells Mitosis occurs in gametes Mitosis results in two daughter cells Mitosis results in genetically identical daughter cells True statements: Mitosis occurs in somatic cells Mitosis results in two daughter cells Mitosis results in genetically identical daughter cells
The types of cells that do not undergo mitosis are nerve cells and muscle cells.
Cytokinesis is cell division and occurs right after mitosis, it is important in cell division in plants and animals.
2 diploid cells
The type of cells that do not undergo mitosis are mature nerve cells and muscle cells.
double what the person already had if mitosis is when cells divide into two cells
Somatic cells undergo mitosis.
The types of cells that do not undergo mitosis are mature red blood cells and nerve cells.
