What do you think this colorful picture shows? If friend guessed that it’s a snapshot of a cell undergoing cell division, you space right. But much more specifically, the image is a lung cabinet stained with fluorescent water undergoing mitosis, throughout early anaphase.
You are watching: During which phase of mitosis do sister chromatids separate to opposite poles of the cell?
Mitosis and Cytokinesis
During mitosis, as soon as the cell nucleus divides, the 2 chromatids that consist of each chromosome separate from every other and move to opposite poles the the cell. This is presented in Figure below. You have the right to watch an animation of the process at the complying with link:http://www.ubraintv-jp.comlogy.arizona.edu/Cell_ubraintv-jp.com/tutorials/cell_cycle/MitosisFlash.html.
Mitosis is the phase of the eukaryotic ubraintv-jp.com cell cycle the occurs in between DNA replication and also the development of 2 daughter cells. What happens during mitosis?
Mitosis actually occurs in 4 phases. The phases are referred to as prophase, metaphase, anaphase, and telophase. Castle are displayed in Figure below and described in greater detail in the following sections.
Metaphase
During metaphase, spindle fibers connect to the centromere of each pair the sister chromatids (see Figure below). The sisters chromatids heat up in ~ the equator, or center, of the cell. This is likewise known together the metaphase plate. The spindle yarn ensure that sister chromatids will separate and go to various daughter cells as soon as the cabinet divides.
Chromosomes, consist of of sister chromatids, heat up at the equator or middle of the cell throughout metaphase.
Anaphase
During anaphase, sister chromatids separate and also the centromeres divide. The sister chromatids room pulled personal by the shortening of the spindle fibers. This is choose reeling in a fish by shortening the fishing line. One sister chromatid move to one pole the the cell, and also the other sister chromatid moves to the contrary pole. In ~ the end of anaphase, every pole that the cell has a complete set of chromosomes.
Cytokinesis
Cytokinesis is the last stage that cell department in eukaryotes and prokaryotes. During cytokinesis, the cytoplasm splits in two and also the cell divides. Cytokinesis occurs somewhat differently in plant and also animal cells, as presented in Figure below. In animal cells, the plasma membrane the the parental cell pinches inward along the cell’s equator until two daughter cells form. In tree cells, a cell plate forms along the equator of the parental cell. Then, a brand-new plasma membrane and cell wall form along every side the the cell plate.
Cytokinesis is the last stage of eukaryotic cell division. It occurs differently in animal (left) and plant (right) cells.
The phases of mitosis are discussed in the video: http://www.youtube.com/watch?v=LLKX_4DHE3I.
The 4 phases of mitosis. Deserve to you describe what happens in every phase?
Summary
Cell department in eukaryotic cells includes mitosis, in which the cell nucleus divides, and also cytokinesis, in i beg your pardon the cytoplasm divides and daughter cell form. Mitosis wake up in 4 phases, referred to as prophase, metaphase, anaphase, and telophase.Explore an ext I
