| As a result, the normal complement of DNA in the micronucleus is 4C during the amitotic division of the macronucleus and cytokinesis. |
| In a typical direct, or amitotic, division the nucleus is constricted in the middle and divides into two daughter-nuclei. |
| Tetrahymena divide by binary fission during vegetative growth, and the micronucleus and macronucleus are propagated by mitotic and amitotic division, respectively. |
| Conversely, in prokaryotes and unicellular eukaryotes, cells divide by amitotic processes, including budding. |
| Cell loss is especially apparent in amitotic tissues, such as central nervous system neurons and cardiac muscle. |
| Cadmium chloride, they have found, will promote growth of the MCF-7 human breast cancer cell line, cells that are normally amitotic in the absence of estradiol. |
