Web18 de dez. de 2012 · These chromosomes are replicated to produce sister chromatids that are held together by cohesins (grey circles around the sister chromatids). During the next stage of meiosis, called Prophase I, chromosomes with similar sequences form pairs and undergo recombination, creating physical links that hold the homologs together. Weba. Microtubules from the spindle poles attach to the kinetochores on the chromosomes. b. In anaphase, the spindle separates sister chromatids and pulls them apart. c. In metaphase, spindle microtubules align the chromosomes at the spindle midpoint. d. Cytokinesis describes the movement of chromosomes. e.

WebEventually, all the sister chromatids will be attached via their kinetochores to microtubules from opposing poles. Spindle microtubules that do not engage the chromosomes are called polar microtubules. These microtubules overlap each other midway between the two poles and contribute to cell elongation. WebThe metaphase checkpoint ensures that all sister chromatids are properly attached to their respective microtubules and lined up at the metaphase plate before the signal is given to separate them during anaphase.
