humen skin cells only live for a few days then they get replaced
It takes about 12-24 hours for a typical human cell(somatic cell) to fully undergo mitosis.
After cell division is completed, it remains for a rather long time in the resting phase.
cells have to divide during mitosis because if they grow too large, materials that pass through the selectively permeable membrane will take to long to get to the organelle that it needs to get to. and when that happens the cell(s) die and your body cannot properly function and you will eventually die
you probably asked this a long time ago but the answer is nuclear division, because interphase is befor cell division. :)
Cell division is a process by which acell, called the parent cell, divides into two or more cells, called daughter cells. Cell division is usually a small segment of a larger cell cycle. This type of cell division ineukaryotes is known as mitosis, and leaves the daughter cell capable of dividing again. The corresponding sort of cell division in prokaryotes is known asbinary fission. In another type of cell division present only in eukaryotes, called meiosis, a cell is permanently transformed into a gamete and cannot divide again until fertilization. For simple unicellular organisms[nb 1] such as the amoeba, one cell division is equivalent to reproduction-- an entire new organism is created. On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings. Cell division also enables sexually reproducing organisms to develop from the one-celled zygote, which itself was produced by cell division from gametes.
That depends on the organism involved. in animals, meoisis occurs during the production of gametes, which undergo no further cell division prior to fertilization. plants and some algae exhibit alternation of generations (I don't want to discuss this one coz it's long and boring).
It depends on the type of cell, and the organism the cell is from. A mammal spends approximately 90%/20 hours of its time during cell division in interphase.
There is not enough room for two complete molecules of DNA. Therefore, when the DNA copy is nearly complete, the replication process stops just long enough for the cell to divide

The longest human cell are nerve cells in the human body. Some of them run the length of the spine all the way to the toes and may be as long as 1.5m in length.
The duration of mitosis of normal epidermis is approximately 90 min.
Chromosomes are invisible except during cell division because the DNA stays in the nucleus. This is to protect it.
