WebApr 9, 2024 · During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator. For example, if the two homologous members of chromosome 1 are labeled a and b, then the chromosomes could line up a-b, or b-a. WebThe chromosomes begin to decondense and return to their “stringy” form. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after … Different cells take different lengths of time to complete the cell cycle. A typical … And our DNA condenses into kind of the condensed form of the chromosomes. …

WebApr 23, 2024 · At the very start of the metaphase stage, the pairs of condensed chromosomes line up along the equator of the elongated cell. Because they are condensed, they can move more easily without becoming tangled. Some biologists actually separate metaphase into two phases: prometaphase, and true metaphase. WebAug 17, 2024 · As you can see in Figure 11.3. 5, the sister chromatids line up at the equator, or center, of the cell. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides. Some spindles do not attach to the kinetochore protein of the centromeres. chief sitting eagle

WebIn metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense. WebAug 17, 2024 · During mitosis, the two sister chromatids that make up each chromosome separate from each other and move to opposite poles of the cell. Mitosis occurs in four … got church
