The Cell Cycle, Cell Cycle Latest Update 100% Correct cytokinesis Complete cytoplasmic separation of the 2 new cells resulting from mitosis. mitosis The process of NUCLEAR division interphase Period of time where a cell carries out cell processes and replicates DNA prior to cell division prophase Chromatin condenses into chromosomes metaphase Chromosomes line up in the middle of the cell anaphase Sister chromatids separate telophase new nuclei begin to reform, chromatids relax chromatid Each half of the chromosome chromosome condensed chromatin; contains DNA that carries genetic information centromere attachment site of sister chromatids cell cycle An ordered sequence of events in the life of a eukaryotic cell; process of growth and division. G1 phase interphase stage of cell cycle where cell grows and carries out metabolic processes G2 phase interphase stage prepares to divide by copying organelles and producing proteins necessary for division S phase interphase stage of cell cycle where cell replicates DNA stage of the cell cycle where the nucleus divides mitosis Cell spends the majority of its life in this stage interphase Checkpoints stop to the cell cycle to check for DNA damage Cancer uncontrolled cell division first stage of mitosis, nuclear envelope disappears, chromosomes condense prophase second stage of mitosis, centrioles move to opposite ends of cell, spindle fibers attach to chromosomes, chromosomes line up in middle metaphase third stage of mitosis, spindle fibers shorten pulling chromosomes apart anaphase fourth stage of mitosis, cells begin to form cleavage furrow (animal) or cell plate (plant) and divide telophase Cytokinesis final stage of the cell cycle, cytoplasm of cells divides and move apart Prophase diagram Identify the stage using the diagram. Metaphase diagram Identify the stage using the diagram. Anaphase diagram Identify the stage using the diagram. Telophase diagram Identify the stage using the diagram. Cytokinesis diagram Identify the stage using the diagram. Centriole organelle of animal cell that aids in cell division Spindle fiber microtubule threads that emerge from centrioles, attach to chromosomes to pull them apart during mitosis reasons for mitosis divides cells that are too large, replaces damaged/dying cells, allows for growth Cleavage furrow a pinching of the cell membrane that begins to form in telophase cell plate method of plant cell division; formation of a new cell wall instead of cleavage furrow Cyclins and Checkpoints Regulation system for the cell cycle Cyclins Signal each stage of the cell cycle to begin Carcinogens cancer causing factors (tobacco, chemicals, UV radiation) steps of mitosis PMAT steps of interphase G1, S, G2 apoptosis programmed cell death end product of the cell cycle 2 identical daughter cells chromatin relaxed form of DNA, present during interphase telomere protective cap made of DNA that is found on the ends of a chromosome nucleus eukaryotic organelle that controls all cellular processes (location of DNA)
