WebFeb 4, 2024 · Regardless, some really important things occur during prometaphase that propel cell division along and that help explain what happens in metaphase. Prometaphase is the phase of mitosis following prophase and preceding metaphase. The short version of what happens during prometaphase is that the nuclear membrane breaks down . WebThe process of chromosome alignment differs between meiosis I and meiosis II. In prometaphase I, microtubules attach to the fused kinetochores of homologous chromosomes, and the homologous chromosomes are arranged at the midpoint of the cell in metaphase I. In anaphase I, the homologous chromosomes are separated. how many foot is 170 cm https://ryanstrittmather.com
