High voltage (1MeV) transmission electron microscopy image of a 0.5 micrometer section of a Chinese hamster ovary cell in metaphase containing a longitudinal section of a chromatid pair, and revealing the fiber-like structure. The image was taken with a specimen tilt of 55 degrees. Grouped with it is an image with a tilt of 45 degrees, providing a pair that affords an oblique stereo view of the chromosome.

Technical Details

Cells in metaphase were fixed, embedded in plastic, and 0.5 um sections cut and stained with uranyl acetate. See also: H. Ris 1981 Steroscopic electron microscopy of chromosomes.
