The Cell Cycle: Ready, Set, Grow...
This quiz was designed to test your knowledge of the cell cycle.
Questions and Answers
- 1.
In the cell cycle, this stage is when DNA is duplicated and proteins are made.
- A.
Interphase
- B.
Cytokinesis
- C.
Metaphase
- D.
Prophase
Correct Answer
A. InterphaseExplanation
During interphase, the cell prepares for division by duplicating its DNA and synthesizing proteins necessary for cell growth and function. This stage is characterized by a period of intense metabolic activity, where the cell carries out its normal functions and prepares for division. It is the longest phase of the cell cycle and consists of three subphases: G1, S, and G2. Therefore, interphase is the correct answer as it accurately describes the stage when DNA duplication and protein synthesis occur.Rate this question:

In this phase of the cell cycle, the plasma membrane pinches until two daughter cells are formed.
Correct Answer
cytokinesis
cytoExplanation
During cytokinesis, the plasma membrane of the cell constricts and pinches inwards, eventually dividing the cell into two daughter cells. This process ensures that each daughter cell receives a complete set of genetic material and other cellular components. The term "cyto" refers to cells, which is relevant to the process of cytokinesis. Therefore, the correct answer is cytokinesis.Rate this question:

Which stages of are NOT a part of mitosis?
- A.
Anaphase, metaphase
- B.
Prophase, telophase
- C.
Interphase, cytokinesis
- D.
Prophase, metaphase
Correct Answer
C. Interphase, cytokinesisExplanation
Interphase and cytokinesis are not stages of mitosis. Interphase is the stage where the cell prepares for division by growing and replicating its DNA. Cytokinesis is the final stage of cell division, where the cytoplasm divides into two separate daughter cells. Mitosis consists of prophase, metaphase, anaphase, and telophase, where the nucleus divides and the chromosomes are separated into the daughter cells.Rate this question:

What is the correct order of mitosis?
- A.
Telophase, anaphase, prophase, metaphase
- B.
Anaphase, metaphase, prophase, telophase
- C.
Metaphase, telophase, anaphase, prophase
- D.
Prophase, metaphase, anaphase, telophase
Correct Answer
D. Prophase, metaphase, anaphase, telophaseExplanation
Mitosis is the process of cell division, which consists of four stages: prophase, metaphase, anaphase, and telophase. In prophase, the chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and the spindle fibers begin to form. In metaphase, the chromosomes line up at the center of the cell and attach to the spindle fibers. In anaphase, the sister chromatids separate and move towards opposite ends of the cell. In telophase, the chromosomes reach the opposite poles of the cell, the spindle fibers disassemble, and the nuclear membrane reforms. Therefore, the correct order of mitosis is prophase, metaphase, anaphase, telophase.Rate this question:

This is a picture of a cell during _____________. The sister chromatids are being pulled apart.
- A.
Interphase
- B.
Anaphase
- C.
Prophase
- D.
Metaphase
Correct Answer
B. AnaphaseExplanation
During anaphase, the sister chromatids are being pulled apart. This is the stage of cell division where the paired chromosomes separate and move towards opposite poles of the cell. The spindle fibers attached to the centromeres of the sister chromatids contract, causing them to move towards opposite ends of the cell. This process ensures that each daughter cell receives a complete set of chromosomes.Rate this question:

During this phase, the nuclear membrane begins to disappear and the spindle fibers begin to form.
- A.
Interphase
- B.
Anaphase
- C.
Telophase
- D.
Prophase
Correct Answer
D. ProphaseExplanation
During the prophase of cell division, the nuclear membrane starts to break down, allowing the genetic material to be exposed. At the same time, spindle fibers, which are responsible for separating the chromosomes, begin to form. This phase marks the beginning of mitosis or meiosis, where the cell prepares to divide into two daughter cells.Rate this question:

Mitosis is the result of uncontrolled division of cells.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Mitosis is not the result of uncontrolled division of cells. Mitosis is a highly regulated process that occurs in eukaryotic cells to ensure the accurate division and distribution of genetic material. It is a part of the cell cycle and is responsible for the growth, development, and repair of tissues in multicellular organisms. The process of mitosis involves the division of the nucleus into two identical daughter nuclei, each containing a complete set of chromosomes.Rate this question:

What are chromosomes made of?
- A.
Cytoplasm
- B.
Centrioles
- C.
RNA and proteins
- D.
DNA and proteins
Correct Answer
D. DNA and proteinsExplanation
Chromosomes are made up of DNA and proteins. DNA is the genetic material that carries the instructions for the development and functioning of living organisms. It contains the genes that determine an individual's traits and characteristics. Proteins, on the other hand, help in organizing and packaging the DNA into a compact structure, allowing it to fit inside the nucleus of a cell. Together, DNA and proteins form the structure of chromosomes, which play a crucial role in the transmission of genetic information from one generation to the next.Rate this question:

At the end of the cell cycle, there are _____ daughter cells.
- A.
4
- B.
3
- C.
2
- D.
1
Correct Answer
C. 2Explanation
At the end of the cell cycle, there are two daughter cells. This is because during the cell cycle, a parent cell divides into two identical daughter cells through a process called mitosis. Each daughter cell contains a complete set of genetic material and is capable of carrying out its own functions independently. Therefore, the correct answer is 2.Rate this question:
