Sixteen cell stage Zebrafish embryo. The first frame shows cells at metaphase. The sequence covers the next four cell cycles. In each prophase, there is a rapid onset of yolk platelet motility. Yolk m...

Serial tomography of embryonic ciliary ganglion spine mat

Images of negatively stained chromatin fibers prepared from tandem arrays of a nucleosome positioning sequence reconstituted with purified histones together with the results of Monte Carlo simulations...

EM images of chromatin fibers reconstituted from tandem arrays of a strong nucleosome positioning sequence flanked by 'linker' DNA, creating fibers containing 22 nucleosomes and a nucleosome repeat l...

Model of the yeast Origin Recognition Complex ORC)complexed with double stranded DNA incorporating a sequence that encodes the replication origin. The 3D structure of the complex with bound DNA was de...

A confocal 4D-stack from a transgenic Drosophila embryo expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) and anti-lamin-B antibodies during prometaphase. The microinje...

Images of negatively stained chromatin fibers prepared from tandem arrays of a nucleosome positioning sequence reconstituted with purified histones. These samples contained 61 repeats of a 197 bp DNA ...

Image shows (actin polymerization at) free barbed ends and F-actin in the lamellipodium of a migrating primary murine embryonic fibroblast. Cell has been mildly permeabilized using saponin during a 2...
