Cell Cycle Quiz

What are the stages of the cell cycle?

• interphase, mitosis, and cytokinesis

• cytokinesis, interphase, and telophase

• telophase, anaphase, and prophase

• prophase, metaphase, and anaphase

Which phase of the cell cycle is the longest?

• Mitosis

• Cytokinesis

• G1 phase

• Interphase

What happens during interphase?

• Cell death, DNA replication, and preparation for cell division

• Cell division, DNA replication, and preparation for cell growth

• Cell growth, DNA repair, and preparation for cell division

• Cell growth, DNA replication, and preparation for cell division

What is the purpose of mitosis?

• The purpose of mitosis is to ensure growth, repair, and replacement of cells in multicellular organisms.

• The purpose of mitosis is to generate energy for the cell.

• The purpose of mitosis is to eliminate damaged cells from the body.

• The purpose of mitosis is to produce gametes for sexual reproduction.

What are the four stages of mitosis?

• interphase, prophase, metaphase, anaphase

• prophase, metaphase, telophase, cytokinesis

• prophase, metaphase, anaphase, interphase

• prophase, metaphase, anaphase, telophase

What is cytokinesis?

• The process of dividing the cytoplasm of a cell into two daughter cells after nuclear division.

• The process of dividing the nucleus of a cell into two daughter cells.

• The process of dividing the cell membrane into two daughter cells.

• The process of combining the cytoplasm of two cells into one daughter cell.

When does cytokinesis occur?

• During cellular respiration

• During DNA replication

• During cell division

• During protein synthesis

What is the difference between mitosis and cytokinesis?

• Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.

• Mitosis and cytokinesis are both involved in the replication of DNA.

• Mitosis and cytokinesis are the same process.

• Mitosis is the division of the cytoplasm, while cytokinesis is the division of the nucleus.

What is the role of the centrosome in cell division?

• The centrosome organizes microtubules and helps separate chromosomes during mitosis.

• The centrosome regulates cell growth during cell division.

• The centrosome produces energy for cell division.

• The centrosome stores genetic information during cell division.

How does the cell ensure accurate DNA replication during the cell cycle?

• The cell ensures accurate DNA replication by relying on external factors.

• The cell ensures accurate DNA replication by skipping the proofreading step.

• The cell ensures accurate DNA replication through proofreading activity of DNA polymerase and checkpoint proteins.

• The cell ensures accurate DNA replication by randomly copying DNA strands.
