High resolution of a daughter micronucleus in anaphase of a dividing cell of Didinium nasutum. The chromosomes are compacted into one large heterochromatic body. Remnants of the mitotic division spind...

Surface rendered models of chromatin organization from tomogram derived from a TEM image of epon section of a freeze-substituted mouse retina. (C) shows the region boxed in CIL:39743 where 4 regions o...

This is a region of a (semithin) longitudinal section of onion root taken from the meristematic zone; this is the undifferentiated region of plant tissue from which new cells are formed. Therefore, it...

Using a camera mounted above the microscope, experts adjust the lens and angle to capture the stain and transfer the image to a computer for processing.

Transmission electron micrograph of the dense fibrous nuclear lamina (here labeled 'nuclear sheath')closely adpressed to the inner membrane of the nuclear envelope(arrow)in an intestinal epithelial ce...

Transmission electron micrograph showing the extensive accumulation of darkly stained heterochromatin at the nuclear periphery typical of many differentiated cells. Heterochromatin is excluded from re...

Transmission electron micrograph of Leydig cell nucleus from the domestic boar contains a region (arrow) thought to represent the single X chromosome which is largely heterochromatic. The chromosome i...

The intracellular mobility of MeCP2 (a methylated DNA-binding protein) followed in a mouse fibroblast stably expressing GFP-MeCP2 through a time series of images captured by confocal microscopy after ...

Tripolar mitosis in a liver cancer cell line. Normally, dividing cells form a single metaphase plate of paired chromosomes which are pulled apart by opposing microtubule spindles. The Z series, obtai...

Transmission electron micrograph of nucleus showing the characteristic features of glutaraldehyde fixation introduced as a primary fixative in 1962 and since used routinely. Chromatin appears differen...
