karyokinesis – מילון אנגלי-אנגלי
karyokinesis
n.
(Biology) splitting of a cell's nucleus; changes which occur during the separation of a cell's nucleus
Mitosis
Mitosis is a part of the
cell cycle in which
chromosomes in a
cell nucleus are separated into two identical sets of chromosomes, and each set ends up in its own nucleus. In general, mitosis (division of the nucleus) is often accompanied or followed by
cytokinesis, which divides the
cytoplasm,
organelles and
cell membrane into two new cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the
mitotic (
M)
phase of an animal cell cycle—the
division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell.
karyokinesis
Noun
1. organic process consisting of the division of the nucleus of a cell during mitosis or meiosis
(hypernym) organic process, biological process
(part-holonym) mitosis
Karyokinesis
(n.)
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.
