Definitions for: Karyokinesis


[n] organic process consisting of the division of the nucleus of a cell during mitosis or meiosis



Webster (1913) Definition: Kar"y*o*ki*ne`sis, n. [NL., fr. Gr. ? a nut,
kernel + ? to move.] (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.
