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 ...
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both ...
The mechanical process of cell division exerts powerful, if microscopic, forces. How do the molecular machines that power it ...
