Exercise 4

A cytogeneticist examines cells in stamen hairs of Tradescantia in an attempt to estimate the duration of the various stages in mitosis and the cell cycle as a whole. She examines 2000 cells and finds 295 cells in prophase, 148 cells in metaphase, 78 cells in anaphase, and 109 cells in telophase. Assuming that the cells are sampled in proportion to the duration of each stage in the cell cycle, what conclusion can be drawn about the relative length of each stage of the cell cycle, including the time spent in interphase
Express each answer as a percentage of the total cell-cycle time.
