Chromosome separation

WebHowever, as soon as they are pulled apart during cell division, each is considered a separate chromosome. What happens to a chromosome as a cell prepares to divide. The chromosome consists of a single chromatid and is decondensed (long and string-like). 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. …
