karyokinesis

In embryology, the series of active changes which take place in the nucleus of a living cell in the process of division. Also written caryocinesis.

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.

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

The process of change that takes place during the division of a cell nucleus at mitosis or meiosis.

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