What is the name of the process in the diagram.
metaphase
mitosis
meiosis
mycosis
Refer to the diagram. Arrange the stages of mitosis in order.
I, II, III, IV, V, VI
VI, II, I, IV, V, III
III, VI, I IV, II, V
V, III, IV, I, II, VI
Refer to the diagram. What is occurring within the cell labeled II?
a cleavage furrow is forming to divide the cell into two daughter cells
DNA is replicated so there are two copies of each chromosome in each daughter cell
chromatin is condensing to form visible chromosomes
the spindle is attaching to chromatids to move them to the middle
Which stage of the cell cycle in the diagram above shows the formation of spindle fibers and chromatin condensing into chromosomes?
I
III
IV
VI
What is the purpose of mitosis
each daughter cell has half the amount of DNA of parent cells
new nuclei have an exact copy of DNA
reproduction of mitochondria and chloroplasts
prevents the occurrence of cancer cells
In order for a cell to successfully divide, the cell must first:
duplicate its genetic information
decrease it's volume
increase in size
decrease it's number of organelles
Sister chromatids are attached to each other at an area called
centriole
centromere
spindle
chromosome
If a cell has 22 chromosomes, how many chromosomes will each of it's daughter cells have after cytokinesis during mitosis?
8
11
22
24
Where does DNA replication occur?
G1
S
G2
M
What occurs at G1?
chromatin condenses to form chromosomes
cleavage of cytoplasm and formation of cell plate
period of growth and development between mitotic divisions
nuclear membrane, nucleolus and chromatin fade
The cell cycle has checkpoints built in to ensure that each cell has met certain criteria before being allowed to move to the next stage. What happens prior to the cell being allowed to enter the G2 stage of the cell cycle?
the cell makes RNA
the nucleus divides
DNA replication occurs
the chromosomes align
What part of the cell clycle results in daughter cells?
mitosis
prophase
cytokinesis
G2 checkpoint
During prophase, chromosomes become visible, the spindle forms and the nucleolus and nuclear envelope disappear. In which cellular process does prophase occur?
mitosis
DNA replication
interphase
growth phase
What kind of cells most likely result from uncontrolled growth due to mutations in genes that control the cell cycle?
nerve cells
bone cells
cancer cells
cardiac cells
During the cell cycle, normal cells exit the G1 phase and enter the G0 phase where they rest. Typically, cells will reenter the cycle at G1 prior to going on to S phase. However abnormal cells such as cancer cells may not be allowed to enter the G0 phase to rest. As a result, these cells will most likely -
mutate during G2 phase
continuously repeat the cycle
die after DNA replication
fail to complete mitosis
Which of the following processes is mort likely affected by cancer drugs
cellular respiration
transport of molecules
cell differentiation
cellular division
As cancerous cells multiply uncontrollably, abnormal tissue masses form. These masses of tissue are called -
tumors
cell bags
alveoli
metastasize
Which of the following structures do plant cells have that animal cells do not?
vacuoles and cell membranes
chloroplasts and mitrochondria
chloroplasts and cells walls
cell walls and cell membranes
Which phase of mitosis is occurring in the cell indicated by the arrow?
prophase
metaphase
anaphase
telophase
Cells pass through a G2 checkpoint before entering mitosis. Ideally, if DNA damage is detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage repaired before cells enter mitosis?
so that another round of DNA synthesis does not have to take place
So that the chromosomes can align a the metaphase plate during mitosis
So that the cytoplasm can be divided equally between the two daughter cells
so that healthy daughter cells are produced, allowing the organism to continue growing
Oncogenes are mutated forms of genes. Oncogenes can transform a cell into a tumor cell. Some tumor cells are benign, while others are malignant. How does the presence of an oncogene lead to the formation of a tumor?
ATP production is inhibited
cell division is unregulated
somatic cell growth is inhibited
antibody activity is unregulated
Fruit fly body cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have ...
16 chromosomes.
46 chromosomes.
8 chromosomes.
4 chromosomes.
which phases are in mitosis ?
interphase
prophase
metaphase
cytokinesis
anaphase
What are the "X" shaped things in the drawing.
PMATs
Chromosomes
Ribosomes
Telophase
Which stage of the Life Cycle of the cell is this cell in (look close-the DNA hasn't formed Chromosomes (X) yet)
Interphase
Prophase
Anaphase
Telophase
Which of the following is the correct order of the Cell Cycle?
Interphase, Mitosis, Cytokinesis
Mitosis, Cytokinesis, Mitosis, Interphase
Prophase, Metaphase, Anaphase, Telophase
Interphase, Prohase, Cytokinesis
