Prophase II is the first step in meiosis II. Like mitosis and meiosis I, the chromosomes condense throughout this step. The centrosomes move to opposite poles and begin to form spindle fibers. Kinetochore proteins assemble on the outer chromatids of each chromosome just as they do in mitosis. The meiotic spindle attaches to the kinetochores, and, as in mitosis, our little kinetochore friend is busy working on those winches on either side of the chromosome. By adjusting the length of the microtubules on each side, the kinetochore can position each chromosome in the middle of the cell. By the end of prophase II, the nuclear membrane has broken down and the meiotic spindle apparatus has assembled.
