Figures 226 (upper) and 227 (lower) from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Examples of mitochondrial DNA from a plant cell (Vicia faba), and from the snake adrena...

This section represents one in a series of serial sections. At this point the two parts of the macronucleus are now connected by a DNA replication band similar to the hypotrichs (e.g. Euplotes). The l...

This animation shows a nucleosome located in its putative binding site on the SWI-SNF remodeling complex from yeast. The atomic structure of the DNA component of the nucleosome based on x-ray diffrac...

Telomeres were isolated from chicken erythrocyte nuclei following restriction endonuclease treatment, and imaged by transmission EM after uranyl acetate negative staining. Like its DNA counterpart, te...

X-ray scattering shows that the nucleated erythrocytes of the amphibian Necturus maculosus (Mud Puppy) contain more ordered chromatin than most nuclei. Here, fibers isolated from these nuclei have bee...

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...

chicken erythrocyte nuclei were allowed to decondense in a low salt high pH buffer, fixed with HCOH, centrifuged onto a carbon coated EM grid, and stained with uranyl acetate. (Spreading technique of ...
