cell cycle - to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells., interphase - The interval between the end of one mitotic or meiotic division and the beginning of another. called also resting stage., G1 phase - the period in the cell cycle from the end of cell division to the beginning of DNA replication, s phase - an interphase stage when a cell's DNA makes another copy of itself, G2 phase - the second growth period of the cell cycle, following DNA replication and preceding prophase, during which the cell forms the materials that make up the spindle, apoptosis - cell death when something goes wrong during the cell cycle, M phase - the period in the cell cycle during which cell division takes place., mitosis - The process by which a single parent cell divides to make two new daughter cells., prophase - the first stage of mitosis or the second division of meiosis in which chromosomes become visible as tightly coiled threadlike structures., metaphase - a stage during the process of cell division (mitosis or meiosis)., anaphase - the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle., telophase - the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed., cytokinesis - the process by which one cell physically divides into two cells., DNA - genetic material that makes up chromosomes, chromatin - a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms, chromosome - A structure found inside the nucleus of a cell, chromatid - one of the two identical halves of a chromosome that has been replicated in preparation for cell division, centromere - the region where the cell's spindle fibers attach, centriole - cell organelle that creates spindle fibers in mitosis, spindle fibers - what centrioles make to move and position the chromosomes, cleavage furrow - a plasma membrane invagination at the cell division site., cell plate - a disk formed in the phragmoplast of a dividing plant cell that eventually forms the middle lamella of the wall between the daughter cells, cancer - a disease that occurs when a cell division step goes wrong,
