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?

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?

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
