Question 1

Which of the following best describes the difference between a haploid and a diploid cell?

Accepted Answer

A haploid cell contains one set of chromosomes, while a diploid cell contains two sets of chromosomes.

Question 2

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

Accepted Answer

S phase

Question 3

Which of the following processes is responsible for the genetic diversity observed in gametes produced by meiosis?

Accepted Answer

Crossing over and independent assortment

Question 4

If a human cell has 46 chromosomes at the start of mitosis, how many chromosomes will each daughter cell have after cytokinesis?

Accepted Answer

46

Question 5

Which equation correctly represents the number of possible chromosome combinations due to independent assortment in gametes, where $$n is $$the haploid number?

Accepted Answer

$$2^n$$

Question 6

What is the primary function of the mitotic spindle during mitosis?

Accepted Answer

To separate chromosomes into daughter cells

Question 7

Which of the following events occurs during prophase of mitosis?

Accepted Answer

Chromatin condenses into visible chromosomes and the nucleolus disappears.

Question 8

A cell is observed with chromosomes aligned in the center of the cell, spindle fibers attached to kinetochores, and the nuclear envelope completely dissolved. Which phase is this cell in?

Accepted Answer

Metaphase

Question 9

Which checkpoint in the cell cycle ensures that all chromosomes are properly attached to the spindle before proceeding?

Accepted Answer

M checkpoint

Question 10

What is the result if cytokinesis does not occur after mitosis?

Accepted Answer

A cell with two nuclei

Question 11

Which of the following statements about homologous chromosomes is correct?

Accepted Answer

They carry the same genes but may have different alleles.

Question 12

Which process is unique to meiosis and does NOT occur in mitosis?

Accepted Answer

Synapsis of homologous chromosomes

Question 13

A cell with 2n = 16 undergoes meiosis. How many chromosomes will each gamete contain?

Accepted Answer

8

Question 14

Which of the following best describes the outcome of nondisjunction during meiosis?

Accepted Answer

Gametes with an abnormal number of chromosomes

Question 15

Which phase of mitosis is characterized by the separation of sister chromatids?

Accepted Answer

Anaphase

Question 16

Which of the following is a function of the non-kinetochore microtubules during mitosis?

Accepted Answer

Pushing the poles of the cell further apart

Question 17

Which of the following is true regarding the products of meiosis II?

Accepted Answer

Four genetically diverse haploid cells are produced.

Question 18

Which of the following best explains why crossing over during meiosis increases genetic variation?

Accepted Answer

It exchanges corresponding segments of non-sister chromatids from homologous chromosomes.

Question 19

Which of the following statements describes a difference between mitosis and meiosis I in a diploid organism?

Accepted Answer

Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I.

Question 20

Which of the following cell cycle checkpoints ensures that the genetic material is fully replicated before mitosis?

Accepted Answer

G2 checkpoint
