Cell Division/ Mitosis Review

What is the role of spindle fibers during mitosis?

• They help separate the chromosomes during cell division.

• They assist in the formation of the nuclear envelope.

• They are responsible for DNA replication.

• They help in the synthesis of ribosomes.

What is the role of checkpoints in the cell cycle?

• They ensure that the cell is ready to proceed to the next phase.

• They promote cell division regardless of conditions.

• They prevent DNA replication from occurring.

• They initiate apoptosis in damaged cells.

What happens during the S phase of the cell cycle?

• DNA is replicated.

• Cell growth occurs.

• Chromosomes are separated.

• Protein synthesis takes place.

What is the outcome of mitosis?

• Two genetically identical daughter cells.

• Four genetically diverse daughter cells.

• One diploid parent cell.

• Two haploid daughter cells.

In which phase of mitosis do chromosomes condense?

• Metaphase

• Anaphase

• Prophase

• Telophase

What is the process called when a cell splits into two?

• Mitosis

• Cytokinesis

• Meiosis

• Binary Fission

What is a key statement of the cell theory?

• All cells come from pre-existing cells.

• All cells are identical in structure and function.

• All living organisms are made up of a single cell.

• All cells can spontaneously generate from non-living matter.

During which phase of mitosis do chromosomes line up in the middle of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

What is the significance of the G1 phase in the cell cycle?

• It is the phase in which the cell grows and prepares for DNA replication.

• It is the phase where DNA is replicated.

• It is the phase where the cell divides into two daughter cells.

• It is the phase where the cell undergoes apoptosis.

What is the final phase of mitosis?

• Metaphase

• Anaphase

• Telophase

• Prophase
