16-cell purple urchin embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated with 40 µM trichostatin A (TSA), an ...

Example of human chromosome labeling and identification using multi-color fluorescence in situ hybridization (FISH) with probes specific for the DNA of individual chromosomes. Using this chromosome p...

Transmission electron micrograph showing part of a decondensed mitotic chromosome. The residual protein 'scaffold' (at bottom) is surrounded by a 'halo' of DNA loops 20 to 24 micrometers long. The en...

Scanning probe 3D image of a single metaphase wheat chromosome, with selected height contours superimposed around the base. Using such images, complete genomic sets of chromosomes can be classified ac...

High resolution of a daughter micronucleus in anaphase of a dividing cell of Didinium nasutum. The chromosomes are compacted into one large heterochromatic body. Remnants of the mitotic division spind...

Microtubules in sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Eight-cell sand dollar embryo; single microtubules gro...

Eight-cell purple urchin embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated with 20 µM nocodazole at time 00:...

Dual-channel spinning-disk confocal time-lapse movie showing kinetochores (Alexa488 labeled CENP-A antibody) in anaphase (red) relative to poleward microtubule flux. Fluorescent speckle microscopy (FS...

Microtubules in live urchin embryos expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Microtubules approach the cortex everywhere before an...

Microtubules in sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Vegetal view, 28-cell sand dollar embryo show astral mi...
