Question 1

Which of the following best describes the primary purpose of mitosis in human cells?

Accepted Answer

To enable growth and repair/replacement of somatic cells

Question 2

During meiosis, how many rounds of cell division occur, and what is the result in terms of chromosome number in the daughter cells?

Accepted Answer

Two rounds; daughter cells have 23 chromosomes

Question 3

Which phase of the cell cycle is characterized by ongoing metabolic activities and preparation for cell division, but not actual division?

Accepted Answer

Interphase

Question 4

A liver cell undergoes mitosis. How many genetically identical daughter cells are produced, and how many chromosomes does each contain?

Accepted Answer

Two daughter cells, each with 46 chromosomes

Question 5

Which of the following statements about meiosis is correct?

Accepted Answer

It produces four daughter cells, each with half the number of chromosomes as the parent cell

Question 6

If a cell spends most of its time in interphase, which of the following best explains why?

Accepted Answer

Interphase is when the cell performs most of its metabolic activities and prepares for division

Question 7

Which of the following is TRUE regarding the chromosome number in human cells after mitosis and meiosis?

Accepted Answer

Mitosis produces cells with 46 chromosomes; meiosis produces cells with 23 chromosomes

Question 8

Which equation correctly represents the chromosome number change during meiosis in humans?

Accepted Answer

$$2n \rightarrow n$$

Question 9

A mutation occurs during meiosis in a male. Which cells are most likely to be affected by this mutation?

Accepted Answer

Sperm cells

Question 10

Which of the following best explains why meiosis is essential for sexual reproduction?

Accepted Answer

It reduces the chromosome number by half, allowing for genetic diversity when gametes fuse

Question 11

During which phase of the cell cycle does DNA replication occur?

Accepted Answer

Interphase

Question 12

A cell in the testes undergoes meiosis. How many daughter cells are produced, and what is their genetic relationship to each other?

Accepted Answer

Four daughter cells, genetically unique

Question 13

Which of the following is NOT a function of mitosis?

Accepted Answer

Production of gametes

Question 14

If a cell fails to complete interphase properly, which of the following is most likely to occur?

Accepted Answer

The cell will divide with incomplete or damaged DNA

Question 15

Which of the following best describes the difference between mitosis and meiosis in terms of genetic outcome?

Accepted Answer

Mitosis produces genetically identical cells; meiosis produces genetically unique cells

Question 16

Which of the following cell types is most likely to be in a continuous state of mitosis throughout life?

Accepted Answer

Skin epithelial cells

Question 17

A patient has a genetic disorder caused by errors in meiosis. Which of the following is the most likely consequence?

Accepted Answer

Abnormal number of chromosomes in gametes

Question 18

Which of the following best explains why interphase is critical for cell division?

Accepted Answer

It is when the cell performs DNA replication and prepares for division

Question 19

Which process is responsible for producing cells that are used in tissue repair and growth?

Accepted Answer

Mitosis

Question 20

If a cell in the ovary undergoes meiosis, what is the expected chromosome number in each resulting daughter cell?

Accepted Answer

$$23$$
