Question 1

Which of the following best describes the difference between sexual and asexual reproduction?

Accepted Answer

Asexual reproduction produces genetically identical offspring, while sexual reproduction increases genetic diversity.

Question 2

Which process is responsible for the production of gametes in humans?

Accepted Answer

Meiosis

Question 3

What is the primary function of mitosis in multicellular organisms?

Accepted Answer

To enable growth and repair by producing identical daughter cells

Question 4

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

Accepted Answer

S phase

Question 5

Which of the following is a type of asexual reproduction?

Accepted Answer

Binary fission

Question 6

What is the difference between diploid and haploid cells?

Accepted Answer

Diploid cells have two sets of chromosomes, while haploid cells have one set.

Question 7

Which equation correctly represents the chromosome number change during meiosis?

Accepted Answer

$$2n \rightarrow n$$

Question 8

Which event during meiosis increases genetic diversity?

Accepted Answer

Crossing over

Question 9

A karyotype can be used to:

Accepted Answer

Identify chromosomal abnormalities such as nondisjunction

Question 10

Which of the following is NOT a function of the cell cycle checkpoints?

Accepted Answer

Promoting uncontrolled cell division

Question 11

Which phase of mitosis is characterized by the alignment of chromosomes at the cell's equator?

Accepted Answer

Metaphase

Question 12

What is the main difference between prokaryotic and eukaryotic chromosomes?

Accepted Answer

Prokaryotic chromosomes are circular and singular, while eukaryotic chromosomes are linear and multiple.

Question 13

Which type of chromosomal mutation involves the loss of a segment of a chromosome?

Accepted Answer

Deletion

Question 14

Which genetic disorder is commonly caused by nondisjunction during meiosis?

Accepted Answer

Down syndrome

Question 15

Which statement about the lytic and lysogenic cycles of viral replication is correct?

Accepted Answer

The lytic cycle results in the destruction of the host cell, while the lysogenic cycle allows the virus to remain dormant.

Question 16

Which of the following best describes binary fission?

Accepted Answer

A process by which prokaryotic cells divide to produce two identical cells

Question 17

Which equation represents the number of chromosomes in a human somatic cell after mitosis?

Accepted Answer

$$2n$$

Question 18

Which process is most likely to result in cancer if cell cycle checkpoints fail?

Accepted Answer

Uncontrolled mitosis

Question 19

Which of the following is a key difference between mitosis and meiosis?

Accepted Answer

Mitosis maintains chromosome number, while meiosis reduces it by half.

Question 20

Which structure is found in both prokaryotic and eukaryotic viruses?

Accepted Answer

Capsid

Cell Division: Reproduction, Chromosomes, Mitosis, Meiosis, and Viral Replication
