Question 1

Which of the following best describes what happens during prophase of mitosis?

Accepted Answer

Chromatin condenses into chromosomes, the nuclear membrane breaks down, and spindle fibers begin to form.

Question 2

During which phase of mitosis do chromosomes align at the center of the cell, forming the metaphase plate?

Accepted Answer

Metaphase

Question 3

What is the main event that occurs during anaphase of mitosis?

Accepted Answer

Sister chromatids are pulled apart to opposite poles of the cell.

Question 4

Which of the following correctly matches the phase of mitosis with its main event?

Accepted Answer

Anaphase: Sister chromatids separate to opposite poles.

Question 5

What is the correct order of the phases of mitosis?

Accepted Answer

Prophase, Metaphase, Anaphase, Telophase

Question 6

Which of the following statements about cytokinesis in animal and plant cells is correct?

Accepted Answer

Animal cells form a cleavage furrow, while plant cells form a cell plate.

Question 7

A scientist observes a cell with chromosomes aligned at the center and spindle fibers attached to centromeres. Which phase is the cell in?

Accepted Answer

Metaphase

Question 8

Which structure is responsible for pulling sister chromatids apart during anaphase?

Accepted Answer

Spindle fibers

Question 9

If a mutation prevents the breakdown of the nuclear membrane during mitosis, which phase would be directly affected?

Accepted Answer

Prophase

Question 10

Which of the following best explains why plant cells require a cell plate during cytokinesis?

Accepted Answer

Plant cells have a rigid cell wall that prevents cleavage furrow formation.

Question 11

A drug inhibits the formation of spindle fibers. Which stage of mitosis would be most directly impacted?

Accepted Answer

Prophase

Question 12

Which of the following is NOT a correct description of a mitotic phase?

Accepted Answer

Telophase: Chromosomes condense further and spindle fibers attach to centromeres.

Question 13

Which mnemonic can help remember the order of mitosis phases?

Accepted Answer

Please Make A Team

Question 14

What is the main difference between mitosis and cytokinesis?

Accepted Answer

Mitosis divides the nucleus, while cytokinesis divides the cytoplasm.

Question 15

Which phase of mitosis is characterized by the reformation of nuclear membranes and the uncoiling of chromosomes?

Accepted Answer

Telophase
