Cell Cycle Quiz: Mitosis, Interphase And Cytokinesis!
(82).jpg "Cell Cycle Quiz: Mitosis, Interphase And Cytokinesis! - Quiz")
This is a cell cycle quiz about mitosis, interphase, and cytokinesis! The cell undergoes different processes when it has duplicated and as the processes differ, so do the results. In mitosis, the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle. What of the other processes? This quiz will help test out how well you know the processes and their results as well. Give it a shot!
- 1.
Why do cells divide when they get too large?
- A.
Transportation of wastes becomes a problem for large cells.
- B.
When a cell is too large, materials can not get to all parts of the cell.
- C.
As a cell grows, the volume increases much faster than the surface area. This causes difficulty with transportation of wastes and nutrients through the cell.
- D.
None of the above.
Correct Answer
C. As a cell grows, the volume increases much faster than the surface area. This causes difficulty with transportation of wastes and nutrients through the cell.Explanation
When the volume is too large, BOTH getting nutrients throughout the cell and removing waste products will be problems.Rate this question:

Which phase in the cell cycle is DNA replicated?
- A.
Prophase
- B.
Interphase, during G1
- C.
Interphase during S
- D.
Interphase during G2
Correct Answer
C. Interphase during SExplanation
S phase: Synthesis of DNA.Rate this question:

Which part of the cell cycle is the nuclear membrane reformed?
- A.
Metaphase
- B.
Anaphase
- C.
Telophase
- D.
Cytokinesis
Correct Answer
C. TelophaseExplanation
During telophase, the nuclear membrane starts to reform around the separated sets of chromosomes. This is because telophase is the final stage of mitosis, where the chromosomes have already been pulled apart and are now moving towards opposite ends of the cell. As the chromosomes reach their respective ends, the nuclear membrane begins to enclose them, forming two separate nuclei. This marks the completion of cell division and the beginning of cytokinesis, where the rest of the cell components divide to form two daughter cells.Rate this question:

Which phase(s) in the cell cycle are the chromosomes visible?
- A.
Interphase and mitosis
- B.
Mitosis
- C.
S, G2, mitosis
- D.
S, G2, interphase and cytokinesis
Correct Answer
B. MitosisExplanation
The chromosomes are first visible in prophase when the coil and thicken. They start to uncoil during telophase.Rate this question:

If the cell is a human cell, how many chromosomes are visible during G1?
- A.
46
- B.
92
- C.
23
- D.
None
Correct Answer
D. NoneExplanation
Well, this might have been a trick question. You can't see chromosomes in G1. They are not visible until they start to coil in prophase. So the answer is 0. (There are 46 chromosomes in human somatic (body) cells).Rate this question:

- 6.
What happens during interphase?
- A.
The cell divides.
- B.
The cell grows and performs its normal functions.
- C.
The cell is in stasis. It is not growing.
- D.
The cell is growing and dividing
Correct Answer
B. The cell grows and performs its normal functions.Explanation
Interphase is when the cell is growing and performing its normal functions. (It will also replicate its DNA in the S phase).Rate this question:

What is the correct order of mitosis?
- A.
Prophase, metaphase, anaphase, telophase
- B.
Prophase, metaphase, anaphase, telophase, cytokinesis
- C.
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
- D.
Prophase, anaphase, metaphase, telophase
Correct Answer
A. Prophase, metaphase, anaphase, telophaseExplanation
Mitosis is only nuclear division: "PMAT": Prophase, Metaphase, Anaphase and TelophaseRate this question:

Which phase(s) of the cell cycle are sister chromatids attached at the centromere?
- A.
G1, S, G2, prophase, metaphase
- B.
S, G2, prophase, metaphase
- C.
S, G2, prophase, metaphase and anaphase
- D.
Prophase, metaphase
Correct Answer
B. S, G2, prophase, metaphaseExplanation
The DNA duplicates in the S phase. The centromere remains to hold the sister chromatids together until anaphase. In anaphase, the spindle fibers shorten, pulling the sister chromatids apart.Rate this question:

Which part of the cell cycle will the sister chromatids line up in the center?
- A.
Prophase
- B.
Metaphase
- C.
Anaphase
- D.
Telophase

B. MetaphaseExplanation

In which phases of the cell cycle does the cell have twice as much DNA than G1?
- A.
S phase, only
- B.
S, G2, Prophase, Anaphase, Metaphase
- C.
S, G2, Prophase
- D.
S, G2, Prophase, Anaphase, Metaphase, Telophase
Correct Answer
C. S, G2, ProphaseExplanation
During the S phase of the cell cycle, DNA replication occurs, resulting in the synthesis of an additional copy of DNA. Therefore, by the end of the S phase, the cell has twice as much DNA as it did in the G1 phase. This doubled amount of DNA persists through the G2 phase, as the cell prepares for mitosis. During prophase, the duplicated chromosomes become visible as distinct sister chromatids, still containing the doubled amount of DNA. Therefore, in S phase, G2 phase, and prophase of mitosis, the cell has twice as much DNA compared to the G1 phase.Rate this question:
