Cell Cycle Quiz

What are the two main phases of the cell cycle?

• Metaphase and interphase

• Telophase and cytokinesis

• Interphase and mitotic phase

• Prophase and anaphase

Which phase of the cell cycle is responsible for DNA replication?

• S phase

• M phase

• G2 phase

• G1 phase

What is mitosis?

• DNA replication

• Photosynthesis

• Cell division

• Protein synthesis

List the stages in the M phase in order.

• Prophase, metaphase, anaphase, telophase, cytokinesis

• Prophase, metaphase, telophase, anaphase, cytokinesis

• Interphase, prophase, metaphase, anaphase, telophase

• Prophase, metaphase, anaphase, telophase, meiosis

How does cancer relate to the cell cycle?

• Cancer occurs when there is uncontrolled cell division.

• Cancer is caused by a lack of cell division.

• Cancer is unrelated to the cell cycle.

• Cancer occurs when there is controlled cell division.

What are cell cycle checkpoints?

• Processes that speed up the cell cycle

• Mechanisms that promote the growth of abnormal cells

• Control mechanisms that regulate cell death

• Control mechanisms that prevent the progression of damaged or abnormal cells

What happens in G1 phase?

• Getting ready for apoptosis (cell death)

• Checking to see if DNA copied correctly

• Synthesizing DNA

• Growth and protein synthesis

What holds the sister chromatids together?

• centromere

• chromatids

• chromatin

• spindle fibers

The cytoplasm divides during this part of the cell cycle.

• Interphase

• Metaphase

• Cytokinesis

• Telophase

What happens in the S phase?

• Synthesizing DNA

• Growth

• Proteins are made

• Getting ready to divide
