In both mitosis and meiosis DNA replication only occurs once, during Interphase and Interphase 1, for mitosis and meiosis, respectively.
Yes, certain cells such as your brain and skeletal muscle cells stop cell division at or around the time of birth and are arrested in a phase of interphase called G0where they no longer divide.
The number of times mitosis occurs in a day depends on the specific type of cell and its growth rate. In rapidly dividing cells, such as those in the bone marrow, skin, or intestinal lining, mitosis can occur multiple times per day. In general, human cells undergo mitosis on average once a day.
They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)
Mitosis a process more simply explained as regeneration of cells, as it is most significant in that process. The cells of our body replicate (clone themselves) as needed. For instance, if you cut your hand, the skin cells will regenerate in the process of mitosis, and so will all cells, except those of reproductive cells which use meiosis. To answer your question: our skin endures micro damage all the time and as regeneration is performed in mitosis, it also occurs all the time.

Interphase
Interphase
Although it varies depending on a cell (some cells never undergo mitosis), a typical cell goes through mitosis when all its organelles have been replicated, its size doubled, and its DNA copied. When all this is finished, the cell condenses its DNA and begins prophase, the first phase of mitosis.A typical cell is in mitosis only about 10% of the times, because the rest of 90% the cell is in interphase, where it goes through normal cell functions instead of dividing.
Most cells spend the majority of their time in interphase because this is when they carry out normal functions such as growth, metabolism, and preparing for cell division. Interphase is a crucial phase in the cell cycle where cells carry out their day-to-day activities before they divide.
Mitosis is the process of separating chromosomes in its cell nucleus into two identical sets in two nuclei within eukaryotic cells. As for when it takes place, I believe it starts after the G2(second gap) stage of Interphase ends.

1 time only which is done during the only interphase in meiosis.
