Whole human female metaphase chromosome from metaphase arrested cell swollen in hypotonic medium and imaged at 1 MeV. This image was taken with a specimen tilt of 55 degrees. Grouped with it is an im...

Light micrograph of onion (Allium cepa) root tip cells stained with acetocarmine to show nuclei and chromosomes. The field includes cells in interphase, prophase, metaphase, and late telophase.

Frog (Xenopus laevis) egg arrested in metaphase of mitosis. Note the tiny metaphase spindle on the top left of the egg. Eggs were fixed in 90% MeOH; 10% (H20 500mM EGTA) and stained for DNA with YoP...

Live mitotic HeLa cell treated with control siRNA, DiOC6(3)to label mitotic membranes (green), and Hoechst 33258 to label chromosomes (blue). Confocal images were taken at 0.118 μm steps along the Z-...

Human melanoma cell undergoing cell division. The chromosomes (blue) have separated and the two daughter cells have almost split apart - only a small bridge of cytoplasm remains. The green staining la...
