tiny structures in animal cells that help to organize microtubules
protein that regulates the cell cycle in eukaryotic cells
phases of the cell cycle that occur between cell divisions; made up of the G1 (gap), S (synthesis), G2 (gap 2), and M (mitosis) phases
first and longest phase of mitosis in which centrioles appear and move to opposite ends of the cell, forming a mitotic spindle
second phase of mitosis in which the chromatids line up at the center of the nucleus and attach to the spindle fibers
third phase of mitosis in which the chromatids are pulled away from each other by the spindle fibers
final stage of mitosis in which a nuclear membrane forms around each set of chromosomes. They appear as chromatin, threads rather than rods.
An assemblage of microtubules and associated proteins that is involved in the movements of chromosomes during mitosis.
identical copies of a chromosome; full sets of these are created during the S(DNA replication) subphase of interphase
a threadlike body in the cell nucleus that carries the genes in a linear order
period from the beginning of one cell division to the beginning of the next
disease in which some of the body's cells grow uncontrollably
area where the two sister chromatids are connected to form a chromosome
process in which the cytoplasm of a cell divides; in animal cells, 'furrowing' occurs; in plant cells, the cell plate forms to make a new cell wall.
