Cell Cycle, Mitosis and Meiosis

Material present in the cytoplasm of all eukaryotic cells, important during cell division; the microtubule-organizing center.
reproductive cells, have only half the number of chromosomes as body cells
the second stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle
a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
any cell in multicellular organism except an egg or sperm
cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases; accounts for 90% of the cycle
cell division in which the nucleus divides into nuclei containing the same number of chromosomes; eukaryotic division
long strands of DNA found in the eukaryotic cell nucleus; condense to form chromosomes; the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins
the fourth and final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes; the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle
the complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes
the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
The final stage of the cell cycle, in which the cell's cytoplasm divides, distributing the organelles into each of the two new cells.
a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells
