High resolution of cell in mitosis. The nuclear envelope of the micronucleus becomes heavily and uniformly labeled with anti-b-tubulin which is not in the form of microtubules. Some tubulin is also pr...

During division the micronucleus contains internal microtubules as well as a layer of b-tubulin, not in microtubular form, on or just inside the nuclear envelope. The section is immunogold labeled wit...

High resolution view during division showing the micronucleus contains internal microtubules as well as a layer of b-tubulin, not in microtubular form, on or just inside the nuclear envelope. The sect...

A high resolution micrograph. Most wild type Tetrahymena have a macronucleus and a micronucleus. The micronucleus, seen here, is essentially nonfunctional during interphase. Its function is to replica...

Except that the nuclear envelope remains intact, micronuclear mitosis occurs in a normal way passing through the four stages of prophase, metaphase, anaphase and telophase. In this example a micronucl...

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; micronucleus; contr...
