What are the phases of the cell cycle? What happens in each phase? How is G0 different
from G1? How long does interphase last in a mammalian cell? How long is the M phase?
Choose checkpoints in the upper left of the box showing the animation of the cell cycle.
What are the three checkpoints? Think about why a cell might have three such
checkpoints.

What are some of the key differences between cellular events in mitosis and meiosis?
Both processes begin in interphase, but the end products are quite different. Mitosis
produces a pair of genetically identical cells, whereas meiosis produces up to four
genetically different cells. At what phase in mitosis do sister chromatids separate? Do
they separate at Anaphase I or II? At what phase does chiasma formation occur? Are the
cells haploid after Meiosis I? After Meiosis II? How many divisions occur in mitosis? How
many in meiosis?
