Description
This section represents one in a series of serial sections. At this point the two parts of the macronucleus are now connected by a DNA replication band similar to the hypotrichs (e.g. Euplotes). The level of this section is approximately half way through the cell. The buccal cavity is reduced and the cytopharynx with its lamellae next to the paroral kinety is curved. Portions of 4 perioral membranelles are seen as well as a food vacuole. TEM taken on 3/12/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 3,800X. Bar = 2µm. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared thicker to accommodate the series.
