Shown is a fibroblast from a Hutchinson-Gilford Progeria syndrome patient which carries a mutation in the gene for lamin A (red), a major component of the nuclear lamina. Also shown is the distributi...

Shown is a fibroblast from a Hutchinson-Gilford Progeria syndrome patient which carries a truncation in the gene for lamin A (red, left image), a major component of the nuclear lamina. The distributio...

Shown are 0.5 micrometer thick confocal image of midplane sections of synchronized 3T3 fibroblasts pulsed for 2 min with CldU and labeled with FITC (green) followed by a variable chase time, and a sec...

Transmission EM of cotyledon of the double knockout oep16.1/16.4 of Arabidopsis thaliana grown in the dark and grown under a normal day/night light regime. Characteristic wildtype thylakoids are seen....

Cells of the symbiotic prochlorophyte Prochloron didemni were separated from its ascidian partner, thylakoids isolated, treated to liberate chlorophyll-containing complexes, and negatively stained pre...

Distribution of Bib1, BubR1 and Mad2(red) on chromosomes assembled from sperm chromatin in nocodazole treated Xenopus oocyte extracts in vitro. Chromosomes are stained with DAPI (blue). Right panels ...

Effect of depletion of the Nup107-160 nucleoporin on spindles assembled in vitro with sperm chromatin and in Xenopus oocyte extracts. Spindles are labeled with tubulin (red) and chromosomes are staine...

Effect of depletion of Nup133 and Nup43 by antibody addition on spindle assembly on sperm chromatin in Xenopus oocyte extract. Spindles (red) were localized by addition of tubulin-rhodamine and chrom...

Fluorescence in situ hybridization (FISH) of chromosome spreads and interphase nuclei of lymphoblastoid cell of higher primates using probes specific to individual chromosomes. The figure illustrates ...

Shown are fibroblasts from a Hutchinson-Gilford Progeria syndrome patient which carries a mutation in the gene for lamin A (red), a major component of the nuclear lamina. The morphology of the envelop...
