mitosis    
n. 有絲分裂,間接核分裂

有絲分裂,間接核分裂

mitosis
n 1: cell division in which the nucleus divides into nuclei
containing the same number of chromosomes

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]


Mitosis \Mi*to"sis\, n. [NL., fr. Gr. ? a thread.] (Biol.)
See {Karyokinesis}.
[1913 Webster]

    What is mitosis? Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes
