Question 2

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

Accepted Answer

S Phase

Question 3

Which of the following statements about asexual reproduction is correct?

Accepted Answer

Asexual reproduction produces genetically identical offspring.

Question 4

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

Accepted Answer

DNA, Nucleosomes, Chromatin, Chromosomes

Question 5

Which structure is responsible for joining two sister chromatids together?

Accepted Answer

Centromere

Question 6

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

Accepted Answer

46

Question 7

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

Accepted Answer

G1 Phase

Question 8

What is the main difference between sexual and asexual reproduction?

Which equation best represents the result of mitosis in a diploid cell?

Accepted Answer

$2n \rightarrow 2n + 2n$

Question 11

A cell that has exited the cell cycle and is performing a specialized function is said to be in which phase?

Accepted Answer

G0 Phase

Question 12

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

Accepted Answer

Production of energy

Question 13

What is the role of histone proteins in the organization of DNA?

Accepted Answer

They help DNA wrap around to form nucleosomes.

Question 14

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

Accepted Answer

Metaphase

Question 15

During which phase of the cell cycle does the cell prepare for mitosis by checking for DNA damage and ensuring all proteins are ready?

Accepted Answer

G2 Phase

Question 16

Which of the following best explains why cancer cells divide uncontrollably?

Accepted Answer

They bypass normal cell cycle checkpoints.

Question 17

Which of the following is the correct definition of a chromosome?

Accepted Answer

A tightly packed structure of DNA and proteins found in dividing cells.

Question 18

If a mutation occurs during DNA replication in the S phase, which of the following is most likely to happen?

Accepted Answer

The mutation will be passed on to both daughter cells after mitosis.

Question 19

Which of the following statements about chromatin is correct?

Accepted Answer

Chromatin is the loosely packed form of DNA found in non-dividing cells.

Question 20

Which of the following must occur before a cell divides?

Accepted Answer

All of the above must occur before a cell can divide.
