Early stage of mitosis
To the right is a cell in the early stages of mitosis, or cell division
This image was taken by the super-resolution microscope (OMX), which offers much greater resolution and detail compared to other forms of light microscopy. The cell shown here is in the ealry stage of mitosis, or cell division. T he chromosomes are stained in purple and the other colors are checkpoint proteins that control the cell cycle (here specifically, proteins that monitor the attachment of microtubules to chromosomes).
