Indirect division, also called karyokinesis<\/strong> or mitosis<\/strong> (Greek: mitos<\/em> \u2014
threads), is a basic mode of division in eukaryotic cells, which have well-
formed nucleus, surrounded by a nuclear envelope. It is observed by a lot of
investigators \u2014 R. Remak, L. Auerbach, A. Schneider, O. B\u00fctschli, I.
Chistyakov, E. Strasburger, etc., but it wins recognition with the works of
Flemming (1882 a, b) and van Beneden (1883 a, b) mentioned in Section 3. 2.
Mitosis is realized in two mutually connected stages: a) division of the
nucleus (karyokinesis); b) division of the cell (cytokinesis). This is
represented in Figure 3\u20138.
In order to be divided, the cell passes its life way, called cell cycle<\/strong> or
generation time<\/strong> (Fig. 3\u20139). Before to start the division it remains in the
so-called interphase<\/strong>, which spans the period between two consecutive
mitoses. For a long interphase was considered \u201cperiod of repose\u201d. It proved
that \u201cthe repose\u201d is not intrinsic to the life. During the interphase there run
intensive preparatory processes. To reach the division of nucleus (phase M \u2014
mitosis), it is necessary to synthesize DNA (phase S \u2014 synthesis). The period
between phase M and the beginning of DNA synthesis is denoted as phase
G\u2081, and the period after the termination of DNA synthesis and phase M \u2014 as
G\u2082. Actually, interphase includes the phases G\u2081, S and G\u2082. Its duration varies
in broad limits for the different kinds of cells (from hours to days, months and
more). Then the division begins. In some lower eukaryotic organisms phase
G\u2081 is absent and after the end of division the cells enter in phase S
immediately.<\/p>\n\n\n\n
