Every biology class learns about mitosis, which involves copying each of a cell's DNA-containing chromosomes, then separating them into two newly created cells. The act of chromosome separation is ...

Scientists have gained new insight into the formation of the spindle, which is the molecular machine that divides up genetic material prior to cell division. Their work focuses on the motor protein, ...

The spindle checkpoint signalling cascade prevents anaphase onset until all chromosomes are correctly attached, through their kinetochores, to spindle microtubules. Molecular interactions between ...
