Topics (4.6 & 4.7) Cell Cycle & Regulation

Multiple Choice

Which of the following describes the purpose of the mitosis cell cycle?

• To make more of the same cells.
• For growth and repair.
• To prevent the cell from becoming too large.
• All of the above.

Multiple Choice

The structure of coiled DNA and proteins that forms in the cells nucleus prior to mitosis is 

• centromere
• centriole
• chromosome
• chromatid

Multiple Choice

The point on the chromosome where the two chromatids are held together is the

• centromere
• centriole
• chromosome
• chromatid

Multiple Choice

Chromosomes are made up of two identical sister _____________.

• chloroplasts
• nuclei
• chromatids 
• gens

Multiple Choice

The first stage of the cell cycle during which the cell matures and prepares to divide and copies its DNA; The stage the cell stays in the most

• interphase
• prophase
• metaphase
• anaphase

Multiple Choice

Which of the following is not a part of interphase?

• G2
• M
• G1
• S

Multiple Choice

Put the stages of mitosis in the correct order.

• prophase - metaphase - anaphase - telophase
• metaphase - anaphase - prophase - telophase
• anaphase - prophase - telophase - metaphase
• telophase - metaphase - prophase - anaphase

Multiple Choice

What is this phase of mitosis?

• prophase
• metaphase
• anaphase
• telophase

Multiple Choice

In what stage are chromosomes separated and moved to opposite poles?

• prophase
• metaphase
• anaphase
• telophase

Multiple Choice

Based on the experiment image, where does the spindle fiber shorten?

• From the spindle pole

• From the centromere on the chromosome

Multiple Choice

What is the division of cytoplasm called?

• chromosome

• mitosis

• cytokinesis

• the cell cycle

Multiple Choice

Where does DNA synthesis happen in eukaryotic cells?

• cytoplasm
• mitochondria
• nucleus
• Golgi apparatus

Multiple Choice

If a parent cell going through mitosis starts with 22 chromosomes, how many chromosomes will be in the daughter cells?

• 22
• 11
• 44
• 15

Multiple Choice

How is cytokinesis different in plant and animal cells?

• In animal cells a cell plate forms between the two daughter cells

• In plant cells a cell plate forms between the two daughter cells

• In plant cells the cytoplasm splits but no cell plate is formed

​Cyclin & Cyclin Dependent Kinases (CDK)

​MPF: Mitosis Promoting Factor, allows mitosis to occur.

• When cyclin levels are high they bind to CDK1 proteins to make MPF.

• ​Cyclin is then degraded so the cell can't divide again until it has gone through all the checkpoints.

Multiple Choice

A type of CdK-cyclin complex that promotes mitosis and peaks in concentration at the end of mitosis.

• p53

• RAS gene

• Platelet Derived Growth Factor (PDGF)

• Maturation (Mitosis) Promoting Factor (MPF)

Multiple Choice

Which of the following is a type of protein that regulates the cell cycle? 

• actin 
• myosin 
• cyclin 
• pepsin 

Multiple Choice

What are cyclins and cyclin dependent kinases?

• regulatory proteins

• carcinogens

• mitotic proteins

• mutagens

Multiple Choice

What is the role of the spindle during mitosis?

• It divides the cell in half.
• It duplicates the DNA.
• It breaks down the nuclear membrane.
• It helps separate the chromosomes.

Multiple Choice

Programmed cell death is called

• apoptosis
• cytokinesis
• interphase
• cancer

Multiple Choice

________________is a critical point where stop and go signals can regulate the cycle

• Metastasis
• Checkpoint
• Malignant
• Benign

Multiple Choice

What usually happens when cells come into contact with other cells?

• they divide more quickly
• they stop growing
• they produce cyclins
• they produce p53

Multiple Choice

the uncontrolled division of cells that results in malignant growth 

• tissues
• cancer
• mitosis
• anaphase

Multiple Choice

The normal function of a tumor suppressor gene is 

• to produce growth signals
• to code for proteins that inhibit, or slow, cell division
• to cause the cell to move faster through the cell cycle
• to attack cancer cells in the body
