Life Span of Cells
Skin cell-two weeks
Red blood cell-4 months
Liver cell-300-500 days
How do we get from one cell to
DNA contains the information to
make more cells (in the nucleus).
The Cell Cycle-DNA is copied and
the cell divides. (Mitosis and
The Cell Cycle
Mitosis-PMAT (Division of cell membrane
Cytokinesis-Division of cytoplasm
How often does your body replace cells in
During which phase do cells go through
Where is the information contained to
make new cells?
What occurs during Mitosis?
