Dicer-deficient oocytes

Dicer-deficient oocytes stained for beta-tubulin and DNA to visualize the meiotic spindle. DNA was counterstained with Sytox green. In the absence of Dicer, mouse oocytes develop abnormal spindles and often fail to complete the first meiotic division, revealing a novel role for small RNAs during meiosis.

Escherichia coli

Escherichia coli cells with fluorescently labeled chromosomal loci.

Drosophila

Drosophila are small flies, typically pale yellow to reddish brown to black, with red eyes. Many species, including the noted Hawaiian picture-wings, have distinct black patterns on the wings. The plumose (feathery) arista, bristling of the head and thorax, and wing venation are characters used to diagnose the family.
