Vocabulary

cell division - The division of a cell in reproduction or growth.
chromatid - One of two identical chromosomal strands into which a chromosome splits longitudinally preparatory to cell division.
centromere - A specialized structure on the chromosome, appearing during cell division as the constricted central region where the two chromatids are held together and form an X shape.
interphase - The period of the cell cycle during which the nucleus is not undergoing division, typically occurring between mitotic or meiotic divisions.
cell cycle - The cycle of growth and asexual reproduction of a cell, consisting of interphase followed in actively dividing cells by prophase, metaphase, anaphase, and telophase.
mitosis - Cell division in which the nucleus divides into nuclei containing the same number of chromosomes.
prophase - The first stage of mitosis.
centriole - One of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosis.
spindle - Shaped achromatic structure, composed of microtubules, along which the chromosomes are distributed in mitosis and meiosis.
metaphase - The stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle.
anaphase - The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle.
telophase - The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
cytokinesis -The division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus.
cyclin - A class of proteins that fluctuate in concentration at specific points during the cell cycle and that regulate the cycle by binding to a kinase.
cancer - A malignant tumor of potentially unlimited growth that expands locally by invasion and systemically by metastasis.
