6551375181G1 PhasePrimary growth phase of the cell0
6551375182S PhasePhase where DNA is replicated1
6551375183G2 PhaseGrowth stage in which the cell prepares for division; organelles replicate and spindle forms2
6551375184InterphaseCollective name for G1, S, and G2 Phases3
6551375185Mitosis (M)Division of the nucleus4
6551375186Cytokinesis (C)Cytoplasm divides; forms 2 daughter cells5
6551375188Chromosomecoiled DNA; visible6
6551375191SpindleConsists of fibers made of proteins; location where chromosomes attach7
6551375193ProphaseChromatin condenses into chromosomes, spindle begins to form, centromeres move away from each other8
6551375195MetaphaseCentrosomes at opposite poles of the cell; chromosomes line up in the middle of the cell9
6551375197TelophaseTwo daughter nuclei form in the cell, nucleus reappears10
6551375198G1 Checkpointchecks cell size, nutrients and growth factors; if a cell has everything it needs, it will copy DNA11
6551375199M Checkpointchecks that all chromosomes are attached to spindle fibers12
6551432723CancerUncontrolled dividing of cells13
6551441848UndifferentiatedDescription of a stem cell14
6551472014HomologousDescribes a pair of chromosomes; one maternal and one paternal15
6551448336Chromatinuncoiled DNA; found during interphase16
6551456239DiploidA cell with two copies of each chromosome17
6551458167HaploidA cell with half the number of chromosomes18
6551460118MeiosisProcess by which gametes are made19
6551481550Crossing OverOccurs during meiosis; increases genetic variation20
6551490912MutationAny change in DNA21
6583667114Binary FissionThe way in which bacteria reproduce; copy and split22
6583699402G0 (G zero)Resting state for cells not dividing23
6583704240Density-Dependent Inhibition (Contact Inhibition)Cells stop dividing when it's too crowded in an area24
6583712238CyclinProtein that increases and decreases throughout the cell cycle and activates enzymes needed for division25
65929385782 DivisionsA description of the events in meiosis26
65929422361 DivisionA description of the events in mitosis27
659294483846Represents the number of chromosomes in a human somatic cell.28
659294796923Represents the number of chromosomes in a human gamete.29
