Answer 9

B) Prophase

Question 10

What happens during telophase?

Answer 10

Nuclear membranes reform around each set of chromosomes.

Question 11

Fill in the blank: The phase before mitosis where DNA is replicated is called _______.

Answer 11

interphase

Question 12

True or False: Mitosis is a form of asexual reproduction.

Answer 12

True

Question 13

What is the term for the region where sister chromatids are joined together?

Answer 13

Centromere

Question 14

What role do centrioles play in mitosis?

Answer 14

They help organize the spindle fibers.

Question 15

Multiple Choice: Which of the following is NOT a phase of mitosis? A) Metaphase B) Anaphase C) S phase

Answer 15

C) S phase

Question 16

What is the significance of the G1 phase in the cell cycle?

Answer 16

It is the phase where the cell grows and prepares for DNA replication.

Question 17

Fill in the blank: The process of nuclear division is called _______.

Answer 17

mitosis

Question 18

What is the difference between mitosis and meiosis?

Answer 18

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

Question 19

True or False: Mitosis occurs in all types of cells.

Answer 19

False

Question 20

What is a chromatid?

Answer 20

One of the two identical halves of a replicated chromosome.

Question 21

What happens during prophase?

Answer 21

Chromatin condenses into chromosomes, and the nuclear envelope begins to break down.

Question 22

Multiple Choice: Which phase of mitosis involves the separation of the centromeres? A) Prophase B) Anaphase C) Telophase

Answer 22

B) Anaphase

Question 23

Fill in the blank: The phase of the cell cycle where the cell prepares for mitosis is called _______.

Answer 23

G2 phase

Question 24

What is the role of the spindle apparatus?

Answer 24

To separate sister chromatids during mitosis.

Question 25

True or False: Cells spend most of their life in the mitotic phase.

Answer 25

False

Question 26

What is the main difference between a benign and malignant tumor in relation to cell division?

Answer 26

Malignant tumors divide uncontrollably and invade other tissues, while benign tumors do not.
