(Phys.org) —Proteins known as histones give structure to DNA, which coils around them like string on spools. But as is so often the case in biology, it turns out there is more to these structures than meets the eye. Scientists ...

(Phys.org) —At the cellular level, the mitotic spindle apparatus is arguably the most complicated piece of machinery in existence. Its basic function is to isolate and separate the chromosomes during cell division. A group ...
(Phys.org) —Researchers at Warwick Medical School have identified the key role played by a team of proteins in the process of mitosis. Working out how to control them may give scientists a way to destroy cancerous cells.

This may look like yet another video of a dividing cell, but there's a catch. You are looking at chromosomes (red) being pulled apart by the mitotic spindle (green), but it's not a cell, because there's no cell membrane. ...
