Question 1

Which process is responsible for producing genetically identical offspring in prokaryotes?

Accepted Answer

Binary fission

Question 2

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

Accepted Answer

S phase

Question 3

What is the correct order of genetic material organization in a dividing cell from smallest to largest?

Accepted Answer

DNA, Nucleosome, Chromatin, Chromosome

Question 4

Which of the following statements about sister chromatids is correct?

Accepted Answer

They are genetically identical and attached at the centromere.

Question 5

A cell that has exited the cell cycle and is performing a specialized function is most likely in which phase?

Accepted Answer

G0

Question 6

Which of the following is NOT a function of cell division in multicellular organisms?

Accepted Answer

Protein synthesis

Question 7

What is the main difference between asexual and sexual reproduction?

Accepted Answer

Asexual reproduction produces genetically identical offspring; sexual reproduction produces genetically diverse offspring.

Question 8

Which structure is responsible for joining sister chromatids together?

Accepted Answer

Centromere

Question 9

If a human somatic cell has 46 chromosomes, how many chromosomes will each daughter cell have after mitosis?

Accepted Answer

46

Question 10

Which phase of the cell cycle is characterized by cell growth and preparation for DNA replication?

Accepted Answer

G1 phase

Question 11

What is the formula for the number of possible chromosome combinations in gametes produced by meiosis, given $$n$$ pairs of chromosomes?

Accepted Answer

$$2^n$$

Question 12

Which of the following best describes the role of histone proteins in the cell?

Accepted Answer

They package DNA into nucleosomes for efficient storage.

Question 13

A mutation occurs in a gene that codes for a protein involved in the cell cycle checkpoint. What is a possible consequence?

Accepted Answer

The cell may divide uncontrollably, leading to cancer.

Question 14

Which of the following events occurs during the M phase of the cell cycle?

Accepted Answer

Chromosome segregation

Question 15

If a dividing cell fails to properly condense its chromatin, which process will be most directly affected?

Accepted Answer

Chromosome segregation during mitosis

Question 16

Which of the following is true regarding chromosomes in a non-dividing cell?

Accepted Answer

Chromatin is loosely packed and not organized into visible chromosomes.

Question 17

A scientist observes a cell with two identical sets of chromosomes attached at a centromere. What stage of the cell cycle is this cell most likely in?

Accepted Answer

After DNA replication, before mitosis

Question 18

Which of the following best explains why sexual reproduction increases genetic diversity?

Accepted Answer

It combines DNA from two parents, resulting in genetically unique offspring.

Question 19

Which process is most important for tissue renewal in multicellular organisms?

Accepted Answer

Mitosis

Question 20

If a cell's DNA is not properly duplicated before division, which of the following is most likely to occur?

Accepted Answer

The daughter cells will have incomplete genetic information.
