AP Biology Ch. 12. The Cell Cycle
Flashcards with terms from Campbell and Reece Et. Al. 8th Edition AP Biology Textbook
Omnis cellula e cellule
Every cell from a cell-latin
The reproduction of cells by one cell splitting to form multiple identical daughter cells.
A cell's endowment of DNA
A cellular structure containing genetic material
All body cells excepting reproductive cells
Reproductive cells-Sperm and Eggs
A complex of DNA and associated protein molecules that make up DNA
Two chromatids, each containing identical DNA make up
the centralized point where sister chromatids are most closely attached.
The divison of the nucleus of a cell to form two new, yet identical, daughter cells
The division of the cytoplasm to form two separate daughter cells, right after mitosis, meiosis I or meiosis II
A type of cell division that has two "rounds" which has an end product of four haploid gametes.
The phase of the cell cycle that includes mitosis and cytokinesis.
preliminary growth of cells in interphase
Synthesis of chromosomes in interphase
further cell growth after chromosomal synthesis during interphase.
1st stage of mitosis, nucleus dissapears, mitotic spindle begins to form, chromosomes condense and become visible with a light microscope
chromosomes condense even more, sister chromatids develop kinetochore
chromosomes line up along the middle of the cell and spindle fibers attach to the centromere of the chromosomes
sister chromatids are separated and pulled to opposite sides of the cell my the spindle fibers
nuclear envelope reforms and cell begins to cleave. chromosomes become less condensed
a subcellular region containing material that functions throughout the cell cycle to organize the cell's microtubules
an assembly of microtubles that is responsible for the movement of chromosomes during cell division
a radial array of short microtubules extending from each centrosome
A specialized region on the centromere that links each sister chromatid to the mitotic spindle.
the imaginary line down the center of a cell on which chromosome line up during metaphase
a shallow groove in the cell surface near the metaphase plate where cleavage can first be noted
Cell Division in bacteria, does not involve mitosis
origin of replication
the specific plate on a chromosome where binary fission begins
A double membrane across the midline of a dividing plant cell, between which the new cell wall forms during cytokinesis.
one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells
enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle.
a non-dividing stage in which cells are in if they have not been initiated to begin cell division
a control point in the cell cycle at which stop and go signals can be used to regulate the cell cycle
cell cycle control system
A cyclically operating set of molecules in the cell that triggers and coordinates key events in the cell cycle.
growth factor protein
protein that initiates cell division
a phenomenon in which cells that become too crowded stop dividing
The requirement that to divide, a cell must be attached to the substratum.
the changing of a normal, healthy cell into a cancerous cell
A mass of abnormal cells that remains at the site of origin.
A cancerous tumor that is invasive enough to impair the functions of one or more organs.
the spread of cancer cells to locations distant from their original site.
