This time-lapse series illustrates the early division up to the four-cell stage of a C. elegans embryo depleted of npl-4 through RNAi. The first C. elegans embryonic division of the P0 zygote is asymm...

Fluorescent micrograph showing transgenic zebrafish embryos expressing green fluorescent protein in the muscle precursor cells (myotomes). The green fluorescence comes from an alpha-actin-GFP transgen...

Transmission electron micrograph of a negatively stained preparation of ribosomes isolated from a 3-day old chick embryo that was maintained in a cold room for 24 hrs. The ribosome crystals seen in ...

Electron micrograph of a cultured Drosophila DL1 cell infected with flock house virus, prepared using chemical fixation followed by routine embedding for electron microscopy. This specimen was prepare...

This movie illustrates the early division up to the four-cell stage of a C. elegans embryo depleted of cdc-48 and atl-1 through RNAi. The first C. elegans embryonic division of the P0 zygote is asymme...
