Which choices accurately match each of the cellular processes to the stage of meiosis in which it occurs? Select all that apply. (5/9 of these are correct) Microtubules attach to kinetochores at the centromere of each homolog in prometaphase I. Microtubules from both poles of the spindle move chromosomes to the center of the cell in anaphase I. Sister chromatids move toward opposite poles of the cell in anaphase II. Crossing over occurs between homologous chromosomes in prophase II. The centromere splits, and the sister chromatids separate in anaphase I. Chromosomes condense to thickened structures that are visible under the microscope in prophase I. Microtubules pull homologous chromosomes toward opposite poles in anaphase I. The nuclear envelope begins to disappear in prophase I. Homologous chromosomes undergo synapsis in prophase II..
