Mitosis involves a single cell division that results in two identical daughter cells, while meiosis consists of two successive divisions, producing four genetically distinct gametes.
The second division of meiosis (meiosis II) appears similar to mitosis, with the only difference being that there are now half as many chromosomes as before. Continuing with the 2n=8 cell example from above, we will observe a cell during metaphase II: During metaphase II, the chromosomes are...
Another difference between mitosis and meiosis is that, during mitosis, there is only one cell division, so the cell goes through the steps of prophase, metaphase, anaphase, and telophase once.However, during meiosis there are two cell divisions, and the cell goes through each phase twice(so ...

The cell cycle. Image fromA&P 6. Most of a cell’s time is spent in Interphase, the largest section of the pie-chart-looking graphic above. But there comes a time in most cells’ lives when they’ve got to reproduce. In the S phase, the cell prepares for this by creating copies of...

kMT intensity was measured from the fluorescence intensity of the entire spindle (top panels, white dashed areas) and also as an average value of 0.25-μm2 sections of kMT fibers at 10 individual kinetochores per cell (bottom panels, white dashed areas). Each point on the chart represents ...
Cohesion fatigue in a large proportion of chromosomes, followed by subsequent cell division, is unlikely to generate viable daughter cells. However, partial or complete chromatid separation, occurring in just one or a few chromosomes, after shorter metaphase delays, may be a common initiating event ...
