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...

This section of Conchophthirus is at the edge of the cortex showing the striated fibers and microtubules that attach to ciliated basal bodies. In particular, enlarged glancing longitudinal views of bo...

High resolution image of the macronucleus of Coleps hirtus. Heterochromatin and nucleoli are seen as smaller and larger stained bodies, respectively, in the macronucleus. Many nuclear pores exist in t...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 1 food vacuole; a segment of the ma...

The figure shows the beginning of the cytopharyngeal ribs of the ribbed wall. The peristome is bordered on one side by the paroral kinety that has 2 rows of basal bodies, of which only one is ciliated...
