Mitosis

Question 1

What is mitosis?

Answer 1

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Question 2

How many stages are there in mitosis?

Answer 2

There are five main stages in mitosis: prophase, metaphase, anaphase, telophase, and cytokinesis.

Question 3

What happens during prophase?

Answer 3

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Question 4

True or False: The nuclear envelope is intact during metaphase.

Answer 4

False.

Question 5

Fill in the blank: During __________, chromosomes align at the cell’s equatorial plane.

Answer 5

metaphase

Question 6

Describe what occurs in anaphase.

Answer 6

In anaphase, sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

Question 7

What marks the beginning of telophase?

Answer 7

Telophase begins when the chromatids reach the poles of the cell and start to de-condense back into chromatin.

Question 8

What is cytokinesis?

Answer 8

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Question 9

Multiple Choice: Which structure is responsible for pulling the sister chromatids apart during mitosis? A) Centrioles B) Spindle fibers C) Chromatin D) Nucleus

Answer 9

B) Spindle fibers

Question 10

What are sister chromatids?

Answer 10

Sister chromatids are identical copies of a chromosome connected by a centromere.

Question 11

True or False: Mitosis occurs in prokaryotic cells.

Answer 11

False.

Question 12

What is the role of the centrioles during mitosis?

Answer 12

Centrioles help organize the mitotic spindle and are involved in the movement of chromosomes.

Question 13

Fill in the blank: The phase of mitosis where the chromosomes first become visible is called __________.

Answer 13

prophase

Question 14

What is the significance of the mitotic spindle?

Answer 14

The mitotic spindle is crucial for the proper separation of chromosomes during mitosis.

Question 15

What happens to the nuclear envelope during prophase?

Answer 15

The nuclear envelope disintegrates during prophase.

Question 16

Multiple Choice: Which phase follows metaphase? A) Prophase B) Anaphase C) Telophase D) Cytokinesis

Answer 16

B) Anaphase

Question 17

What is the main difference between mitosis and meiosis?

Answer 17

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Question 18

True or False: Each daughter cell has the same number of chromosomes as the parent cell after mitosis.

Answer 18

True.

Question 19

What is the role of chromosomes during mitosis?

Answer 19

Chromosomes ensure that DNA is accurately distributed to daughter cells during cell division.

Question 20

Fill in the blank: The phase in which the cell prepares for mitosis is called __________.

Answer 20

interphase

Question 21

What is the purpose of checkpoints in the cell cycle?

Answer 21

Checkpoints ensure that the cell is ready to proceed to the next phase of the cell cycle and that any DNA damage is repaired.

Question 22

Multiple Choice: During which phase do the chromosomes de-condense? A) Prophase B) Metaphase C) Anaphase D) Telophase

Answer 22

D) Telophase

Question 23

What happens to the spindle fibers at the end of mitosis?

Answer 23

The spindle fibers disassemble after the chromosomes have been separated and the daughter cells are formed.
