High resolution image of the macronucleus of Coleps hirtus. Heterochromatin and nucleoli are seen as smaller and larger stained bodies, respectively, in the macronucleus. Many nuclear pores exist in t...

Image shows a metaphase spread revealing the 46 human chromosomes (blue). Telomeres have been labeled using PNA-FISH and appear as pale dots at the ends of each chromatid.

Image of the scopula, the stalk forming region at the aboral end of the cell body of Opercularia coarctata. A group of basal bodies each gives rise to a modified cilium that gives rise to a cylinder o...

Telomeres isolated from chicken erythrocyte nuclei following restriction endonuclease treatment, and imaged by transmission EM after uranyl acetate negative staining. Specimen was also labeled with im...

Fragile X chromosome made visible by atomic force microscopy (AFM). The arrow indicates the fragile site. Additional AFM chromosome images are available as CIL 38987, 39000, and 38915.

Scanning probe/atomic force microscope image of human chromosome 1. Additional scanning probe chromosome images are available as CIL 38987, 39000, and 39013.

Scanning probe/atomic force microscope image of human chromosomes in a metaphase spread. Additional scanning probe images of chromosomes are available as CIL 39000, 38915, and 39013.

High Voltage (1MeV) TEM image of a 'thick' section of polytene chromosome from salivary gland of 3rd instar larva of Drosophila melanogaster showing the band-interband organization. This image was cap...

High voltage (1MeV) transmission electron microscopy image of an isolated metaphase chromatid pair from a mouse A9 cultured cell, showing the fiber-like structure and several pieces of attached membra...
