Chromosome separation
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. WebMay 26, 2000 · This temporal separation forms the basis for the cell cycle's partition into four phases—G 1, S, G 2, and M—and it has played a central role in the evolution of eukaryotic organisms. Meiosis, during which two rounds of chromosome segregation follow a single round of duplication, requires separable S and M phases.
