TEM images of reconstituted chromatin prepared from 12-mer tandem repeats of a strong nuclear positioning sequence and purified histones. Samples were fixed with glutaraldehyde, applied to carbon film...

TEM image of epon section of a freeze-substituted mouse retina illustrating the unusual distribution of heterochromatin in rod receptor nuclei where the compact heterochromatin is centrally located. C...

TEM images of reconstituted chromatin prepared from 12-mer tandem repeats of a strong nuclear positioning sequence and purified histones. Samples were compacted in the appropriate salt, and mildly cro...

TEM image of frozen hydrated soluble chromatin isolated from chicken erythrocyte nuclei and vitrified in low salt. Polynucleosomes adopt an irregular zigzag fiber conformation (a,b,k), and show a 'ste...

TEM image of frozen hydrated soluble chromatin isolated from COS-7 cells and vitrified in 15 mM monovalent ions. The chromatin adopts an irregular zigzag fiber conformation. See Fig 2 in J Bednar et ...

Early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, in which 6000 nuclei will form, followed by cellularization (Foe and Albert...

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...
