Moves chromosomes in a cell
Nettet17. jul. 2024 · Chromosomes move to the opposite cell poles. Similar to mitosis, microtubules such as the kinetochore fibers interact to pull the chromosomes to the cell poles. Unlike in mitosis, sister chromatids remain together after the homologous chromosomes move to opposite poles. At the end of anaphase I of meiosis, the cell … NettetCultured normal cells move and proliferate until they become confluent and form cell–cell junctions. After the establishment of cell–cell junctions, they arrest cell movement and …
