ETYM New Lat., from Greek mitos a thread.
Cell division in which the nucleus divides into nuclei containing the same number of chromosomes.
Cell division, with division of nucleus first.
In biology, the process of cell division by which identical daughter cells are produced. During mitosis the DNA is duplicated and the chromosome number doubled, so new cells contain the same amount of DNA as the original cell.
The genetic material of eukaryotic cells is carried on a number of chromosomes. To control movements of chromosomes during cell division so that both new cells get the correct number, a system of protein tubules, known as the spindle, organizes the chromosomes into position in the middle of the cell before they replicate. The spindle then controls the movement of chromosomes as the cell goes through the stages of division: interphase, prophase, metaphase, anaphase, and telophase. See also meiosis.
