The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets.

The process in which tubulin alpha-beta heterodimers begin aggregation to form an oligomeric tubulin structure (a microtubule seed). Microtubule nucleation is the initiating step in the formation of a microtubule in the absence of any existing microtubules ('de novo' microtubule formation).

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle.

Any process that modulates the frequency, rate or extent of replication and segregation of genetic material in the embryo.

The series of events in which a temperature stimulus (hot or cold) is received and converted into a molecular signal.

Any process in which a centrosome is maintained in a specific location within a cell and prevented from moving elsewhere.

Any process that modulates the frequency, rate or extent of mitotic cytokinetic process.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.
