mitosis
Karyokinesis Kar"y*o*ki*ne`sis (k[a^]r`[i^]*[-o]*k[-i]*n[=e]"s[i^]s), n. [NL., fr. Gr. ka`ryon a nut, kernel + kinei^n to move.] 1. (Biol.) The indirect division of cells in which, prior to division of the cell protoplasm, complicated changes take place in the nucleus, attended with movement of the nuclear fibrils; -- opposed to {karyostenosis}. The nucleus becomes enlarged and convoluted, and finally the threads are separated into two groups which ultimately become disconnected and constitute the daughter nuclei. Called also {mitosis}. See {Cell development}, under {Cell}. [1913 Webster]

2. The changes that occur in the nucleus of a cell, especially movements of the chromosomes, in the process of cell division. [PJC]
