Cell Cycle And Mitosis
Questions and Answers
- 1.
What is the first stage of mitosis?
- A.
Interphase
- B.
Prophase
- C.
Anaphase
Correct Answer
B. ProphaseExplanation
Prophase is the first stage of mitosis. During prophase, the chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and the spindle fibers begin to form. This stage prepares the cell for the separation of its genetic material in the subsequent stages of mitosis.Rate this question:

What are the stages of the cell cycle in order?
- A.
Interphase, prophase, metaphase, anaphase, telephase, cytokinesis
- B.
Prophase, metaphase, telephase, anaphase, cytokinesis, interphase
- C.
None of the above
Correct Answer
A. Interphase, prophase, metaphase, anaphase, telephase, cytokinesisExplanation
The correct answer is interphase, prophase, metaphase, anaphase, telephase, cytokinesis. This is the correct order of the stages of the cell cycle. Interphase is the longest phase where the cell grows and prepares for division. Prophase is the first stage of mitosis where the chromosomes condense. Metaphase is the stage where the chromosomes line up in the middle of the cell. Anaphase is the stage where the sister chromatids separate and move to opposite ends of the cell. Telephase is the stage where the nuclear membrane reforms around the separated chromosomes. Cytokinesis is the final stage where the cell divides into two daughter cells.Rate this question:

What stage is this?
- A.
Telophase
- B.
Metaphase
- C.
Anaphase
Correct Answer
C. AnaphaseExplanation
Anaphase is the correct answer because it is a stage of mitosis or meiosis where the sister chromatids separate and move towards opposite poles of the cell. During anaphase, the microtubules of the spindle apparatus shorten and pull the chromosomes apart. This stage is characterized by the visible movement of the chromosomes towards the poles of the cell.Rate this question:

What happens in Interphase?
- A.
DNA makes copies of its self
- B.
Chromosomes form
- C.
Clevage starts happening
Correct Answer
A. DNA makes copies of its selfExplanation
In Interphase, DNA makes copies of itself. This is the phase of the cell cycle where the cell prepares for cell division by duplicating its genetic material. The DNA replication process ensures that each daughter cell receives a complete and identical set of genetic information. This is a crucial step in cell division as it ensures the accurate transmission of genetic material to the newly formed cells.Rate this question:

Interphase is part of Mitosis
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Interphase is not a part of mitosis. Interphase is the phase of the cell cycle where the cell grows and prepares for cell division. It includes three stages: G1 phase, S phase, and G2 phase. Mitosis, on the other hand, is the process of cell division that occurs after interphase. It consists of four stages: prophase, metaphase, anaphase, and telophase. Therefore, the statement that interphase is part of mitosis is false.Rate this question:

During cytokinesis the two cells formed are called daughter cells
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
During cytokinesis, the process of cell division, the cytoplasm of the parent cell divides into two, resulting in the formation of two daughter cells. These daughter cells are genetically identical to each other and to the parent cell. Therefore, the statement "During cytokinesis the two cells formed are called daughter cells" is true.Rate this question:

Anaphase takes the longest in the cell cycle
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Anaphase is a phase in the cell cycle where the sister chromatids separate and move towards opposite poles of the cell. It is a relatively short phase compared to other phases such as interphase or prophase. Therefore, anaphase does not take the longest in the cell cycle, making the answer "False" correct.Rate this question:

The 3rd step in the cell cycle is ________________.
Correct Answer
metaphaseExplanation
In the cell cycle, metaphase is the third step. During metaphase, the chromosomes align themselves in the middle of the cell, forming a metaphase plate. This alignment is crucial for the accurate distribution of chromosomes during cell division. The correct answer is metaphase.Rate this question:
- 9.
There are _____________ stages in Mitosis
Correct Answer
4
fourExplanation
Mitosis is the process of cell division, where a single cell divides into two identical daughter cells. It consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes condense and the nuclear envelope breaks down. In metaphase, the chromosomes align at the center of the cell. Anaphase involves the separation of sister chromatids to opposite poles of the cell. Finally, during telophase, the nuclear envelope reforms and the chromosomes decondense. Therefore, the correct answer is 4 or four stages in mitosis.Rate this question:
