Questions and Answers

1.

What is the name of the attachment point between sister chromatids in a chromosome?
- A.
  
  Centrioles
- B.
  
  Centromeres
- C.
  
  Spindles
- D.
  
  Membranes
Correct Answer
B. Centromeres

Explanation
Centromeres are the attachment points between sister chromatids in a chromosome. During cell division, the centromere plays a crucial role in ensuring that each daughter cell receives the correct number of chromosomes. It acts as a binding site for the spindle fibers, which are responsible for separating the sister chromatids and distributing them equally to the daughter cells. Therefore, centromeres are essential for maintaining the integrity and stability of the genetic material during cell division.

2.

What is the name of the microtubule fibers that pull the sister chromatids apart?
- A.
  
  Centromeres
- B.
  
  Membranes
- C.
  
  Ligands
- D.
  
  Spindles
Correct Answer
D. Spindles

Explanation
Spindles are the microtubule fibers responsible for pulling the sister chromatids apart during cell division. These structures form during mitosis and attach to the centromeres of the sister chromatids, exerting force to separate them and ensure equal distribution of genetic material to the daughter cells. Spindles play a crucial role in the process of cell division and are essential for maintaining the integrity of the genome.

The pinching off of the cell membrane that creates two new cells (after mitosis) is called
- A.
  
  Interphase
- B.
  
  Metaphase
- C.
  
  Anaphase
- D.
  
  Cytokinesis
Correct Answer
D. Cytokinesis

Explanation
Cytokinesis is the process of pinching off the cell membrane to create two new cells after mitosis. During cytokinesis, the cytoplasm of the parent cell divides into two separate daughter cells, each with its own nucleus and organelles. This process ensures that each new cell receives the appropriate amount of genetic material and cellular components. Interphase, metaphase, and anaphase are all different stages of the cell cycle that occur before cytokinesis.

Which phase of mitosis is shown in the picture?
- A.
  
  Anaphase
- B.
  
  Metaphase
- C.
  
  Prophase
- D.
  
  Telophase
Correct Answer
B. MetapHase

Explanation
The correct answer is metaphase. In metaphase, the chromosomes align themselves along the equatorial plane of the cell. This alignment is clearly visible in the picture provided. The chromosomes appear to be lined up in a single file, indicating that the cell is in metaphase.

5.

Which phase of mitosis is shown in the picture?
- A.
  
  Prophase
- B.
  
  Telophase
- C.
  
  Anaphase
- D.
  
  Metaphase
Correct Answer
B. TelopHase
6.

Which phase of mitosis is shown in the picture?
- A.
  
  Telophase
- B.
  
  Metaphase
- C.
  
  Anaphase
- D.
  
  Prophase
Correct Answer
D. PropHase

Explanation
The correct answer is prophase. In prophase, the chromosomes condense and become visible under a microscope. They pair up and the nuclear membrane starts to break down. This is the first phase of mitosis where the cell prepares for division by organizing its genetic material.

7.

Which phase of mitosis is shown in the picture?
- A.
  
  Anaphase
- B.
  
  Prophase
- C.
  
  Telophase
- D.
  
  Metaphase
Correct Answer
A. AnapHase

Explanation
The correct answer is anaphase. Anaphase is the phase of mitosis where the sister chromatids separate and move towards opposite poles of the cell. In the picture, it is likely that the chromosomes are being pulled apart and moving towards opposite ends of the cell, indicating anaphase.

What is the name of the structures responsible for generating the spindle fibers?
- A.
  
  Centromeres
- B.
  
  Membranes
- C.
  
  The funky hot chocolates
- D.
  
  Centrioles
Correct Answer
D. Centrioles

Explanation
Centrioles are the structures responsible for generating the spindle fibers. During cell division, centrioles play a crucial role in organizing and guiding the formation of the spindle apparatus, which helps separate the chromosomes. They are found in pairs and are located near the nucleus of animal cells. Centromeres, on the other hand, are regions of DNA that hold sister chromatids together during cell division and are not directly involved in generating spindle fibers. Membranes and the funky hot chocolates are unrelated to spindle fiber generation.
