Whatdo cells needtodo between divisions to make sure that afullset of DNA gets passedon toeach daughter cell?the cells need to duplicate its DNAGizmo Warm-upO n the SIMULATION pane of theCelt DivisionGizmo™, check that theCycle Lengthis set to1 2 hours. ClickPlay () , observe until the maximum number of cells is shown, and then clickPause () .Look at the cells. Do they all look the same?yesCells that are in the process of dividing are saidtobe inmitosisorcytokinesis .Cells that arenot dividing arein interphase.Check theMagnifybox and move the cursor over the cells.Of the 100 cells shown, how many are in the process ofdividing?1 9Select the BAR CHART tab, and turn onShow numerical values.How many cells are in the interphase stage of their life cycle?8 1Based on these two observations, would you say that a cell spends most of itslife cycle in interphase or in mitosis/cytokinesis?interphase
