WebMeiosis: Anaphase II During anaphase II, the chromatids are pulled apart by the spindle fibers. Now they are classified as chromosomes, not chromatids. The chromosomes move apart to opposite ends of the cell (Fig. 14). Figure 14. Anaphase II of meiosis. (Image by Marjorie Hanneman.) Previous Page Next Page Mitosis and Meiosis and the Cell Cycle WebMay 27, 2024 · Figure: Anaphase II in Meiosis. Image Source: Wikipedia (Ali Zifan). This is the phase after metaphase 2 whereby the remaining centromeric cohesins which are not protected by the Shugoshin anymore are cleaved. This allows the separation of the sister chromatids which are then singly referred to as sister chromosomes.
Web(prophase, metaphase, anaphase, and telophase). However, in meiosis, nuclear division occurs twice during Meiosis I and Meiosis II, and each stage of meiosis is comprised of four phases: meiosis I (prophase 1, metaphase 1, anaphase 1, and telophase 1) and meiosis II (prophase 2, metaphase 2, anaphase 2, and telophase 2). WebOct 27, 2024 · This stage is characterized by the movement of chromosomes to both poles of a meiotic cell via a microtubule network known as the spindle apparatus. This mechanism separates homologous chromosomes into two separate groups. In anaphase I, the main goal of the spindle apparatus is apparent.
