Which of the following stages of meiosis involves division of centromere?
Metaphase I
Metaphase II
Anaphase II
Telophase
To solve this problem, we need to identify the stage of meiosis where the division of centromeres occurs.Let's analyze each option:Metaphase I: - During metaphase I, homologous chromosomes align at the metaphase plate. - The centromeres do not divide at this stage; instead, homologous chromosomes are separated. - Therefore, centromere division does not occur in metaphase I.Metaphase II: - In metaphase II, chromosomes align at the metaphase plate similar to mitosis. - However, the centromeres still do not divide at this stage. - Therefore, centromere division does not occur in metaphase II.Anaphase II: - During anaphase II, the centromeres divide, allowing sister chromatids to separate and move towards opposite poles. - This is the stage where centromere division occurs, leading to the separation of sister chromatids.Telophase: - Telophase is the stage where the chromosomes reach the poles and begin to de-condense. - The centromeres have already divided by this stage. - Therefore, centromere division does not occur in telophase.Based on the analysis, the correct answer is Anaphase II, where the division of centromeres occurs.Thus, the correct option is Option 3: Anaphase II.
