MITOSIS Mitosis is the process that facilitates the equal partitioning of replicated chromosomes into two identical groups. Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups is a process that can be observed in virtually all eukaryotic cells. Both the alignment and separation processes are the consequence of the chromosomes interacting with filamentous …

…between the newly separating daughter cells. Vesicles movement and aggregation in the spindle midzone is facilitated by a microtubule network known as a phragmoplast. This basket shaped structure forms in late anaphase or early telophase and disassembles about the time that the vesicles begin to coalesce. Nuclear division, or mitosis, typically occupies 5-10%of the total cycle. The cycle may take as little as 20 minutes in a bacterial cell, although it typically takes 8-24 hours.
