When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes ...

The mechanical process of cell division exerts powerful, if microscopic, forces. How do the molecular machines that power it ...

During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes split correctly into the two cells. Spindle fibers—complex machinery ...

During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes split correctly into the two cells. Spindle fibers - complex ...

When a cell divides, spindle fibers (green) form from centrosomes at each end of the cell and guide the chromosomes (purple), ensuring they are correctly divided between the two new cells. Credit must ...

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...

During cell division, the pericentriolar matrix (PCM; blue lines) expands. In C. elegans, the main structural protein of the PCM is SPD-5, which, upon activation, binds to γ tubulin complexes (purple ...
