Unit 4: Life of a cell review

Why is the Cell Cycle often represented as a circle?

• Because it is easy to draw

• Because cell cycles has a distinct beginning and end point

• to highlight the checkpoints

• to show that it repeats over and over

Which stage of the cell cycle is MOST critical for ensuring that daughter cells are identical?

• G1

• S

• Prophase

• G2

Select all stages of interphase?

• G₁

• S

• G₂

• Mitosis

In which stage of the cell cycle does the cell split into two?

• Mitosis

• G₁

• Cytokinesis

• S

_____ is the uncontrolled growth of cells, often resulting in a tumor or mass of abnormal cells

• Cancer

• Apoptosis

• Radiation

Apoptosis is

• mysterious cell death

• programmed cellular mutation

• mysterious cellular mutation

If you look at a cell under a microscope, which phase is it MOST likely to be in?

• Cytokinesis

• M phase

• Interphase

What does DNA Replication mean?

• DNA is made.
• DNA makes new cells. 
• DNA copies itself.
• DNA starts the cell cycle.
