Length of the Cell Cycle • How long does it take for a cell to go through one cell cycle? It all depends on the cell. A human liver cell, for example, completes one cell cycle in about 22 hours, as shown in the graph. Study the graph and then answer the following questions. - Cell Division

Length of the Cell Cycle• How long does it take for a

cell to go through one cell cycle? It all depends on the cell. A human liver cell, for example, completes one cell cycle in about 22 hours, as shown in the graph. Study the graph and then answer the following questions.

Length of the Cell Cycle

– The longest curved arrow represents the cell’s interphase; the shortest represents cytokinesis; and the middle one represents mitosis.

• Reading Graphs:

– What do the three curved arrows outside the circle represent?

- Cell Division

Length of the Cell Cycle

– Interphase

• Reading Graphs:

– In what stage of the cell cycle is the wedge representing growth?

- Cell Division

Length of the Cell Cycle

– 10 hours

• Interpreting Data:

– In human liver cells, how long does it take DNA replication to occur?

- Cell Division

Length of the Cell Cycle

– Interphase

• Drawing Conclusions:

– In human liver cells, what stage in the cell cycle takes the longest time?
