How do chromosomes move during anaphase

WebDuring anaphase A, the chromosomes move to the poles and kinetochore fiber microtubules shorten; during anaphase B, the spindle poles move apart as interpolar microtubules elongate and slide past one another. Many cells undergo both anaphase A and B motions, but, in some cases, one or the other motion dominates. WebMovement of the chromosomes during anaphase would be most affected by a drug that. ... The chromosomes are “reeled in” by the contraction of spindle microtubules, motor proteins of the kinetochores move the chromosomes along the spindle microtubules, and nonkinetochore spindle fibers serve to push chromosomes in the direction of the poles. ...

WebJul 17, 2024 · In anaphase I of meiosis, the following events occur: Chromosomes move to the opposite cell poles. Similar to mitosis, microtubules such as the kinetochore fibers interact to pull the chromosomes to the cell poles. Unlike in mitosis, sister chromatids remain together after the homologous chromosomes move to opposite poles. WebDuring anaphase, the sister chromatids separate and move to opposite ends of the cell. Lastly, during telophase, a nuclear envelope forms around each set of chromosomes, and the chromosomes start to uncoil. Then, cytokinesis occurs (however, it is not a phase of mitosis). During cytokinesis, the cytoplasm divides, creating two new daughter cells. highcraft windows https://markgossage.org
