Bio week 9+10 - Sheet1

the process by which a single cell generates new daughter cells

a method of eukaryotic cell division that results in daughter cells that are genetically identical to the parent cell

method of eukaryotic cell division that results in daughter cells that have half the genetic information of the parent cells

a stage of the cell cycle in which normal metabolic function occurs, and cell prepares for cell division

cell gathers nutrients and other resources from its environment and performs normal metabolic functions

stage in which DNA synthesis (replication) occurs

final preparations for mitosis

1st stage of mitosis. Chromosomes condense. Spindle fibers form. Nuclear membrane disassembles. Nucleolus disappears.

cellular organelles comprised of microtubules. assist in cell division

3rd stage of mitosis. chromosomes align at the equatorial plane of the cell

4th stage of mitosis. sister chromatids move toward opposite ends of the cell

a multi protein complex attached to each chromatid at the centromere. causes shortening of the spindle fibers to pull the chromatid toward the pole.

the site where the chromatids are attached, formed of nitrogenous bases

spindle fibers disassemble. nuclear membrane re-forms. chromosomes uncoil. nucleolus re-forms.

process during which the cell contents are split between the two new daughter cells

an indentation of the plasma membrane that pinches in toward the center during cytokinesis

code for proteins that encourage cell division

code for proteins that discourage cell division

gene that identifies if the cell’s DNA is damaged before DNA synthesis. If damaged, p53 causes the cell to self-destruct

process whereby a cell digests itself from the inside out.

agents that mutate or chemically damage DNA

mutagens that cause cancer

mass of cells not normally found in a certain portion of the body

cell mass that does not fragment and spread beyond its original area of growth
