Chapter 8: ActivitiesActivity 8.1 The Cell Cycle |
 |
The cell cycle is a series of steps in
which the cell is prepared to reproduce itself by mitosis. During the cell cycle, the DNA
in chromosomes is replicated. The resulting sister chromatids are then segregated into the
nuclei of the two daughter cells such that one copy of each chromosome is included in
both daughter cells. Careful control is maintained at checkpoints during certain stages of
the cell cycle to ensure that DNA replication is complete, that DNA molecules are
undamaged, and that the partitioning of chromatids into the future daughter cells is done
correctly.
