Webb(16 pts.) Consider the cell cycle. a. A cytogeneticist examines cells in stamen hairs of the spiderwort plant Tradescantia, to estimate the duration of the various stages of mitosis and the cell cycle as a whole.She examines 2000 cells and finds 320 cells in prophase, 150 cells in metaphase, 80 cells in anaphase, and 120 cells in telophase. Webb[1] [2] It stimulates the mitotic and meiotic phases of the cell cycle. MPF promotes the entrance into mitosis (the M phase) from the G 2 phase by phosphorylating multiple proteins needed during mitosis. MPF is activated at the end of G 2 by a phosphatase, which removes an inhibitory phosphate group added earlier.

WebbProphase: The chromosomes condense into X-shaped structures that can be easily seen under a microscope.
