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 ...
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 ...
Scientists studying zebrafish larvae noticed something weird. Skin cells seemed to be dividing without replicating their DNA. They confirmed that what they were seeing was real, upending what we ...
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 ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...
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 ...
