WebSelect the two that apply. After chromosome separation is complete, a network of microfilaments forms near the plane of cell division that will separate the two new cells. The cell plate consists of the plasma membrane and cell wall that will eventually separate the two daughter cells. WebIntroduction to Chromosome Movement: Chromosomes are involved in a series of directed movements during both mitosis and meiosis. With the separation of the sister chromatids/homologues at anaphase, the equilibrium is broken, the chromosomes move towards the poles at the rate of about 1 pm/min. Chromosome segregation is the process in eukaryotes by which two sister chromatids formed as a consequence of DNA replication, or paired homologous chromosomes, separate from each other and migrate to opposite poles of the nucleus. This segregation process occurs during both mitosis and meiosis. Chromosome segregation also occurs in prokaryotes. However, in contrast to eukaryotic chromosome segregation, replication and segregation are not temporally separated. … theorg hinweise
