Question

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. if the complete cell cycle requires 24 hours, what is the average duration of metaphase in these cells?

Answer 1

The average duration of M phase can be determined by adding up the hours spent ineach stage of mitosis. In these cells, M phase lasts 4.8 hours. The table shows thatmetaphase requires 0.24 hours, or 14.4 minutes
