When the cell begins to pull apart, the replicate and original chromosomes are separated. The prokaryote chromosome is much easier to manipulate than the eukaryotic one. We thus know much more about the location of genes and their control in prokaryotes. One consequence of this asexual method of reproduction is that all organisms in a colony are genetic equals. Commonly the two processes of cell division are confused.
Mitosis deals only with the segregation of the chromosomes and organelles into daughter cells.
Eukaryotic chromosomes occur in the cell in greater numbers than prokaryotic chromosomes. The condensed replicated chromosomes have several points of interest. The kinetochore is the point where microtubules of the spindle apparatus attach. The area where both chromatids are in contact with each other is known as the centromere the kinetochores are on the outer sides of the centromere. Image from W.H.
