- cell division
- a Anchoring junctions that prevents cells subjected to mechanical stress from being pulled apart; two adjacent cells are attached. formed from protein plaques in the the cell membranes linked by protein filaments
- b Second Stage of Cell division: Centromeres of duplicated chromosomes are aligned at plate. chromosomes become attached to spindle fibers
- c A the resting phase between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
- d 3rd phase; the chromatids of each chromosome separate at the centromere and move in opposite poles of the spindle.
- e Process by which a cell divides into two new daughter cells

ribonucleic acid(RNA) → nucleic acid found in all living cells: carries the organism's hereditary information.
triplet → A substance produced by a living organism that acts as a catalyst to bring about a specific chemical reaction
tight junction → Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
gap junction → Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
translation → the process whereby genetic information coded in messenger RNA and used to assemble proteins.
