Questions and Answers
- 1.
What is a Spindle?
- A.
Region where two sister chromatids are joined tightly together
- B.
A slender rounded rod with tapered ends used in hand spinning to twist and wind thread from a mass of wool or flax held on a distaff.
- C.
Final Stage of Mitosis
- D.
Framework of Microtubules that guide the movement of Chromosomes
Correct Answer
D. Framework of Microtubules that guide the movement of ChromosomesExplanation
A spindle refers to the framework of microtubules that guide the movement of chromosomes during cell division. This structure is essential for ensuring that each daughter cell receives the correct number of chromosomes. The spindle fibers attach to the chromosomes and pull them apart, allowing them to move to opposite ends of the dividing cell. This process is crucial for the equal distribution of genetic material and the formation of two genetically identical daughter cells.Rate this question:

Microtubules grow from how many centrosomes?
Correct Answer
2
4
6
12Explanation
Microtubules grow from centrosomes, which are organelles found in animal cells. Each animal cell typically contains two centrosomes, which serve as the main organizing centers for microtubule growth. Therefore, microtubules can grow from either two, four, six, or twelve centrosomes, depending on the specific cell and its stage of division.Rate this question:

A disk containing cell wall material is called a?
Correct Answer
Cell plate
Nuclei
Daughter CellsExplanation
A disk containing cell wall material is called a cell plate. This structure forms during cell division in plant cells and eventually develops into a new cell wall that separates the two daughter cells. Nuclei and daughter cells are not specific to the formation of the cell wall material, so they are not the correct answer in this context.Rate this question:

How many stages are in the Cell Cycle?
Correct Answer
6
5
1
3Explanation
The correct answer is 6. The cell cycle consists of six stages: interphase (G1, S, and G2 phases), mitosis (prophase, metaphase, anaphase, and telophase), and cytokinesis. During interphase, the cell grows and replicates its DNA. Mitosis is the process of cell division, where the replicated DNA is separated into two identical sets. Cytokinesis is the final stage, where the cell physically divides into two daughter cells. Therefore, there are a total of six stages in the cell cycle.Rate this question:

What is Mitosis?
- A.
Process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed.
- B.
Process by which the cytoplasm of a cell is divided into two.
- C.
Stage of the cell cycle when a cell is actively divided.
Correct Answer
A. Process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed.Explanation
Mitosis is the process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed. During mitosis, the duplicated chromosomes condense and align at the center of the cell. They then separate and move towards opposite ends of the cell, forming two identical sets of chromosomes. Finally, the cell divides into two daughter cells, each with its own nucleus containing the same number of chromosomes as the parent cell. This process ensures the equal distribution of genetic material to the daughter cells and is crucial for growth, development, and tissue repair in multicellular organisms.Rate this question:
