Cell Cycle and Mitosis Quiz Questions and Answers
- 1.
Name the phase during which the mitosis of the chromosomes line up along the middle of the dividing cell.
- A.
Prophase
- B.
Metaphase
- C.
Anaphase
- D.
Telophase
Correct Answer
B. MetapHaseExplanation
During metaphase, the chromosomes align themselves along the equatorial plane of the cell, forming a single line called the metaphase plate. This alignment ensures that each daughter cell will receive an equal number of chromosomes during cell division. The spindle fibers attach to the centromeres of the chromosomes, allowing them to be pulled apart during the subsequent phase of mitosis. Therefore, metaphase is the correct phase during which the chromosomes line up along the middle of the dividing cell.Rate this question:

The two main stages of the cell cycle are called:
- A.
Mitosis and interphase
- B.
Telophase and cytokinesis
- C.
Interphase and anaphase
- D.
Cytokinesis and mitosis
Correct Answer
A. Mitosis and interpHaseExplanation
The cell cycle consists of two main stages: mitosis and interphase. Mitosis is the process of cell division where the nucleus divides into two identical daughter cells. Interphase is the period between cell divisions where the cell grows, duplicates its DNA, and prepares for the next division. These two stages are crucial for the growth and reproduction of cells.Rate this question:

The first phase of mitosis is called ___________.
- A.
Prophase
- B.
Anaphase
- C.
Metaphase
- D.
Interphase
Correct Answer
A. PropHaseExplanation
The correct answer is prophase. Prophase is the first phase of mitosis, where the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle fibers start to form. During prophase, the genetic material is prepared for division and the cell begins to transition into the next phase of mitosis.Rate this question:

Sea stars are genetically different from each other and from their parents. These genetic differences are the result of:
- A.
Mitosis
- B.
Cloning
- C.
Asexual reproduction
- D.
Sexual reproduction
Correct Answer
D. Sexual reproductionExplanation
Genetic differences in sea stars and their differences from their parents primarily result from sexual reproduction and asexual reproduction. Sexual reproduction involves the combination of genetic material from two parents, resulting in offspring with genetic diversity.Rate this question:

A protein called p53 can keep cells from dividing. To prevent cell division, this protein most likely stops ___________.
- A.
Osmosis
- B.
Mitosis
- C.
Respiration
- D.
Mutation
Correct Answer
B. MitosisExplanation
The protein p53 is known to prevent cell division. Mitosis is the process by which cells divide and replicate themselves. Therefore, it is most likely that p53 stops mitosis to prevent cell division. Osmosis is the movement of water across a selectively permeable membrane, respiration is the process of converting glucose into energy, and mutation refers to changes in the DNA sequence. None of these processes are directly related to cell division, making mitosis the most likely option.Rate this question:

When the DNA in a cell is uncoiled and spread throughout the nucleus, this process is called chromatin. State true or false.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Chromatin is the complex of DNA and proteins that make up chromosomes within the nucleus of eukaryotic cells. When the cell is not dividing, the chromatin is uncoiled and dispersed throughout the nucleus, making the DNA accessible for transcription and replication. This diffuse form of DNA is essential for the cell to carry out its normal functions. During cell division, the chromatin condenses into tightly packed chromosomes, which are easier to separate and distribute to daughter cells.Rate this question:

DNA in a cell is copied during:
- A.
G1 phase
- B.
G2 phase
- C.
Cytokinesis
- D.
S phase
Correct Answer
D. S pHaseExplanation
During the S phase of the cell cycle, DNA replication occurs. This is the phase where the cell's DNA is copied to produce two identical sets of chromosomes. The S phase is a critical step in cell division as it ensures that each daughter cell receives a complete and accurate copy of the genetic material. Therefore, the correct answer is S phase.Rate this question:

The spindle fibers are produced by the ________.
- A.
Centrioles
- B.
Nucleus
- C.
Chromosomes
- D.
Chromatin
Correct Answer
A. CentriolesExplanation
Centrioles are responsible for producing spindle fibers. Spindle fibers are essential for cell division as they help separate the chromosomes and ensure that each daughter cell receives the correct number of chromosomes. Therefore, centrioles play a crucial role in the process of cell division by producing spindle fibers.Rate this question:

Cleavage furrows form in which type of cells?
- A.
Plants
- B.
Bacteria and plants
- C.
Animal
- D.
All of the above
Correct Answer
C. AnimalExplanation
Cleavage furrows are a feature of animal cells during cell division, specifically during cytokinesis. They are formed as the cell membrane pinches inwards, dividing the cytoplasm into two separate daughter cells. This process is essential for the growth and development of animal organisms. In contrast, bacteria and plants do not form cleavage furrows during cell division. Therefore, the correct answer is animal.Rate this question:

Cells spend most of their time in _____ phase.
- A.
Cytokinesis
- B.
Prophase
- C.
Mitosis
- D.
Interphase
Correct Answer
D. InterpHaseExplanation
The correct answer is interphase because during interphase, cells spend the majority of their time preparing for cell division. This is the longest phase of the cell cycle and is characterized by growth, DNA replication, and preparation for mitosis. Cytokinesis is the final stage of cell division where the cytoplasm divides. Prophase is the first stage of mitosis where the chromosomes condense and become visible. Mitosis is the process of cell division where the replicated chromosomes are separated into two daughter cells.Rate this question:
