The Cell Cycle
Problem : What is the approximate cell cycle duration in fast-dividing mammalian cells? Is this the same for all cells?
Problem : Which phase of the cell cycle—M phase, G1, S phase, or G2—has the most variability in its duration?
Problem : In cells that undergo very rapid cell division, which phases are decreased or eliminated?
Problem : In normal mammalian cells, which take longer: the processes that lead to chromosome duplication or those that lead to cell division?
Problem : How can the amount of DNA present in a cell give an indication of where in the cell cycle a particular cell may be?
