Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a ...

If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

CAPTION: (Top) Condensins seem to act as a molecular crosslinkers to make loops. (Bottom, left) Condensins (red) locate around chromosome center. (Bottom, right) Nucleosomes around the periphery ...
