Cell Cycle (Mitosis) Quiz25f

What is the role of the spindle during mitosis?

• It helps separate the chromosomes.
• It breaks down the nuclear membrane.
• It duplicates the DNA.
• It makes the chromosomes visible.

Cell division (Mitosis) is represented in the figure below by the letter______________.

• A G1
• B S
• C G2
• D Mitosis

Which pair is correct? (correct event that happens in that phase)

• G1 phase(interphase), DNA replication
• G2 phase(interphase), preparation for mitosis
• S phase(interphase), cell division
• M phase(mitosis), cell growth

______________________series of events that cells go through as they grow and divide.

• Cell Cycle
• Cytokinesis
• Mitosis
• Telophase

Which of the following regulate(s) the cell cycle?

• growth factors
• cyclins/kinases
• p53 gene
• all of the above

Which of the following is a factor that can stop normal cells from growing?

• contact with other cells
• growth factors
• a cut in the skin
• cyclin that has been taken from a cell in mitosis

Which of the following is a correct statement about the events of the cell cycle?

• Little happens during the G1 and G2 phases of interphase.
• DNA replicates during cytokinesis after mitosis
• The M(mitosis) phase is usually the longest phase of the cell cycle
• Interphase consists of the G1, S, and G2 phases, and it the longest phase of the cell cycle

When during the cell cycle is a cell’s DNA replicated?

• G1-(interphase) phase
• G2-(interphase) phase
• S-(interphase) phase
• M-(mitosis) phase

What is the phase of Mitosis called that is the last step of cell division, when chromosomes move in opposite directions so two new cells can be formed from one?

• telophase
• anaphase
• cytokinesis
• metaphase
• prophase

During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?

• prophase
• telophase
• metaphase
• anaphase
