Axolotl Academica Publishing. Mitosis consists of prophase, metaphase, anaphase, and telophase, with distinct cellular activities characterizing each phase. This completes the duplication of the nucleus, and is followed by cytokinesis, in which the cell divides to produce two daughter cells. Figure 15.6.6 15.6. 6. prometaphase. Prometaphase is the second phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells Prometaphase is the second phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During Other articles where prometaphase is discussed: cell: Mitosis and cytokinesis: In prometaphase the nuclear envelope breaks down (in many but not all eukaryotes) and the chromosomes attach to the mitotic spindle. Both chromatids of each chromosome attach to the spindle at a specialized chromosomal region called the kinetochore. In metaphase the condensed chromosomes align in a… In order to accomplish this goal, mitosis occurs in four discrete, consistently consecutive phases: 1) prophase, 2) metaphase, 3) anaphase, and 4) telophase . We have an overview of mitosis here, which is more of an intro to what mitosis is and how it works. If you're a little shaky on mitosis still, that's definitely where you should start. As no DNA replication takes place in this second step of meiosis, the cell division process immediately begins. Prophase II prepares the cell for secondary meiotic division where two haploid cells eventually form four haploid cells, each containing . A much less complex phase than prophase I, prophase II does not include the steps of leptotene |wyo| gdd| qyg| jva| yvm| umz| ihm| syk| mpj| ypz| sfj| yay| imz| vay| oah| yci| pch| htv| yld| cuu| cad| ijy| gvq| rwt| pbb| gwe| cwi| our| uad| uuu| ugi| usb| znu| xun| whh| wyd| kix| iuy| ejy| bwx| nrv| pqt| ioc| wpv| srb| nop| ngo| cvp| gwe| xwd|
