During telophase, a step in the cell cycle, ___
the cell begins to separate into two new cells
the cell duplicates its genetic material

What would be the result if mitosis were not accompanied by cytokinesis?
two cells, each with their own nucleus
one cell with no nucleus
one cell with two nuclei
two cells, each without a nucleus
Part of the cell cycle controls the repair of damaged DNA. If this step is unsuccessful, the abnormal cell division that typifies some types of cancer could result. During which part of the cell cycle would this repair occur?
G1
S
G2
M

Mitosis, a stage of the cell cycle, involves
one step: cytokinesis
two steps: prometaphase and metaphase
four steps: prophase, metaphase, anaphase and telophase
four steps:interphase, metaphase, telophase and cytokinesis
What disorder results when human body cells lose the ability to respond to cyclins, the internal regulatory signals that control cell growth?
cellulitis
diabetes
hemophilia
cancer
Which diagram represents a plant cell close to the final stage of mitosis?
Mitosis is important to the growth of organisms because it allows an organism to___
increase its number of cells.
prevent cell death
stop unnecessary functions
change genetic material
The process of mitotic cell division normally results in the production of
one cell with the same number of chromosomes as the parent cell.
four cells with half the number of chromosomes as the parent cell.
two cells with half the number of chromosomes as the parent cell.
two cells with the same number of chromosomes as the parent cell.
The list below describes several events that occur during the process of mitosis.
A. Chromosomes line up in the middle of the cell
B. Spindle fibers pull the sister chromatids apart at the centromere
C. Nucleus begins to dissolve
D. Nucleus forms around the separate sets of chromosomes
E. Spindle fibers begin to form
Which sequence represents the correct order of these events?
A→D→E→B→C
A→B→C→D→E
B→D→A→C→E
C→E→A→B→D
If single-celled organisms did not undergo the cell cycle, they could not___
reproduce.
die
replicate RNA
function
During metaphase, a step in the cell cycle, a cell ___
forms two new nuclear envelopes for chromosomes
moves its chromosomes to opposite poles of the cell.
stimulates its chromatin to condense into a chromosome.
aligns its chromosomes in the middle of the cell.
The cell cycle involves an early stage called Gap 2, during which a cell
divides into two cells.
develops a second nucleus.
prepares for division.
shrinks and fragments.
Erica wants to demonstrate the process of mitosis in a rabbit cell. She creates the four models shown.Which model correctly shows the end result of mitosis?
Model 1 because during mitosis, two daughter cells receive half of the chromosomes of the parent cell.
Model 2 because during mitosis, one daughter cell receives the same number of chromosomes as the parent cell.
Model 3 because during mitosis, two identical daughter cells receive the same number of chromosomes as the parent cell.
Model 4 because during mitosis, four daughter cells receive one quarter of the chromosomes of the parent cell.
The diagram illustrates the process of cell division.What is the significance of anaphase in this process?
Anaphase ensures that each daughter cell receives half the number of chromosomes as the parent cell.
Anaphase ensures that each daughter cell receives different chromosomes than the parent cell.
Anaphase ensures that each daughter cell receives twice as many chromosomes as the parent cell.
Anaphase ensures that each daughter cell receives the same number of chromosomes as the parent cell.
The final stage of mitosis involves ___
the replication of DNA
chromosomes moving to opposite ends of the cell
the elongation of the cell
the formation of mitochondria in the middle of the cell
Which process is represented in the diagram above?
A zygote becoming fertilized
An animal replacing damaged cells
A gamete reproducing sexually
A white blood cell engulfing bacteria
What occurs during G1?
Chromatin condenses to form chromosomes
Cleavage of cytoplasm and formation of cell plate
Period of growth and normal cell functions
Nuclear membrane, nucleolus, and chromatin fade
What gender (male or female) and age experiences the highest rate of pancreatic cancer?
Lysogenic viruses do not ___
inject their DNA into the host cell
reproduce and lyse (break open) the host cell immediately
become dormant and divide with the cell’s DNA
infect a host cell
Which of the following is not a cell but has the ability to reproduce within a living cell?
A bacterium
A virus
An alga
A yeast
Patients with HIV/AIDS develop secondary infections and cancers due to their condition. Which type of cells are primarily affected by HIV/AIDS?
muscle cells
white blood cells
nerve cells
bone cells
Invading the host cell enables the virus to ___
synthesize oxygen
reproduce.
obtain nutrients.
expand.
Mr. Hernandez shares with his class that his dog has the parvovirus and had to be taken to the vet. A student asks Mr. Hernandez if he too has the virus and if the class should be worried. Which explanation below is the most accurate answer Mr. Hernandez could give?
He is infected and could possibly become sick in the next few days, but because he is an adult, his immune system will protect him.
The virus has entered his body but does not make him sick because he is taking an antibiotic.
Every virus has a specific kind of host cell it attaches to, and this virus only infects dogs, not humans.
A virus cannot transfer from one host to another without direct contact.
