The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division. The cell cycle process whereby 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 by which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets. Any process by which a microtubule is maintained in a specific location in a cell. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. The cell cycle process whereby chromosomes are aligned at the metaphase plate, a plane halfway between the poles of the mitotic spindle, during mitosis. The cell cycle process whereby sister chromatids establish stable attachments to microtubules emanating from opposite spindle poles. The process by which spindle microtubules become physically associated with a chromosome. A cellular process that is involved in the progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. The alignment of chromosomes at the metaphase plate, a plane halfway between the poles of the spindle.
