During mitosis, the chromosomes eventually separate to opposite ends of the cell so that the cell can divide into two. Mitosis is the process where one cell replicates and becomes two daughter cells. The chromosomes move... More »

Sister chromatids move because kinetochore microtubules attach to them during metaphase and shorten during anaphase. As they shorten, the mirocrotubules pull each sister chromatid toward an opposite pole of the cell, ens... More »

During mitosis, the nucleus of an eukaryote cell splits into two. The parent cell goes through other stages of division before forming two genetically identical daughter cells, which are also able to duplicate. More »

Homologous chromosomes do not pair during mitosis, so there is no opportunity for crossing over to occur. Crossing over between non-sister chromatids of homologous chromosomes occurs in meiosis during prophase I. More »

Chromosomes become visible during prophase, the stage of mitosis during which the nuclear envelope disappears and the chromosomes shorten and condense. After prophase, chromosomes remain visible until mitosis completes. More »

Chromatin condenses to form chromosomes during prophase of mitosis, and during prophase I and prophase II of meiosis. Chromatin is a dense, complex fibrous structure composed of associated proteins and molecules of deoxy... More »

The chromosomes in a cell's nucleus coil during prophase of mitosis in order to facilitate mobility. The chromosomes and the DNA become coiled and condensed during prophase. More »
