Cells

What does DNA Replication mean?

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

During what phase of the cell cycle does cell division occur?

• Interphase
• M phase
• S phase
• G2 phase

During what phase of the cell cycle is DNA replicated?

• G1 phase
• S phase
• G2 phase
• M phase

During what phase of the cell cycle does the cell grow?

• G1 phase
• S phase
• M phase
• Cytokinesis

During what phase of the cell cycle does the cell prepare for mitosis?

• G1 phase
• S phase
• G2 phase
• M phase

Put the following stages of the cell cycle in order: G2, S, G1, M. 

• G1, S, G2, M
• S, G1, G2, M
• G1, M, G2, S
• M, G1, S, G2

Put the following actions in order: DNA replicates, cell grows, cell divides, cell prepares for mitosis. 

• DNA replicates, cell grows, cell prepares for mitosis, cell divides
• cell grows, cell prepares for mitosis, DNA replicates, cell divides
• cell grows, DNA replicates, cell prepares for mitosis, cell divides
• DNA replicates, cell prepares for mitosis, cell grows, cell divides

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

What is the result of the cell cycle?

• Three cells

• Four daughter cells

• Two identical cells

• One clone cell

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

• Cancer

• Apoptosis

• Radiation
