The very first and longest step of mitosis is prophase. Throughout prophase, dyed condenses right into chromosomes, and the nuclear envelope, or membrane, division down.

You are watching: When do chromatids line up at the equator of a cell


During metaphase, spindle fibers connect to the centromere of every pair the sister chromatids. The sisters chromatids heat up in ~ the equator, or center, the the cell. The spindle fibers ensure the sister chromatids will certainly separate and go to different daughter cells when the cell divides.
During anaphase, sisters chromatids separate and the centromeres divide. The sister chromatids room pulled apart by the shortening the the spindle fibers. This is choose reeling in a fish through shortening the fishing line. One sister chromatid move to one pole of the cell, and also the other sister chromatid moves to the opposite pole. In ~ the end of anaphase, each pole that the cell has actually a complete set of chromosomes.
During telophase, the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle likewise breaks down, and new nuclear membranes form.
Cytokinesis is the final stage that cell division in eukaryotes as well as prokaryotes. Throughout cytokinesis, the cytoplasm splits in two and the cell divides.
Type of cell department in i beg your pardon the variety of chromosomes is decreased by half and 4 haploid cell result
The atom envelope begins to rest down, and also the chromosomes condense. Centrioles start relocating to the opposite poles of the cell, and a spindle begins to form. Importantly, homologous chromosomes pair up, which is unique to prophase I. In prophase that mitosis and meiosis II, homologous chromosomes do not type pairs in this way.
Spindle fibers affix to the paired homologous chromosomes. The combine chromosomes line up along the equator the the cell. This occurs only in metaphase I. In metaphase of mitosis and also meiosis II, the is sisters chromatids the line up along the equator the the cell.
Spindle fibers shorten, and also the chromosomes of each homologous pair start to different from every other. One chromosome of each pair moves toward one pole that the cell, and also the various other chromosome moves towards the the opposite pole.
The spindle breaks down, and new nuclear membrane form. The cytoplasm of the cabinet divides, and two haploid daughter cell result. The daughter cell each have actually a arbitrarily assortment of chromosomes, v one from every homologous pair. Both daughter cells walk on to meiosis II.
The nuclear envelope division down and the spindle begins to kind in each haploid daughter cabinet from meiosis I. The centrioles also start to separate.

The spindle breaks down, and brand-new nuclear membranes form. The cytoplasm ofeach cell divides, and also four haploid cell result. Each cell has actually a unique combination of chromosomes.
