number in a stage x 100 total sample size Enter your calculated values in the data table Mitosis Number of Cells Percent of Total Counted Interphase Prophase Metaphase Anaphase Telophase Total cells 100% 2. The percentage of cells in each phase reflects the amount of spends in each of the phases. For example, if 10% of the cell prophase, and the cell cycle was 12 hours long, you would e about 1.2 hours (12 h x 0.10 = 1.2 h). Based on the informat calculate how long each phase was for your sample and rec below. My Answer: Mitosis Time in hours (12 Hours tota Interphase
