What does DNA stand for?

• Deoxyribonucleic Acid

• Dioxyribonucleic Acid

• Deoxyribonuclear Acid

• Deoxyribonucleic Base

What is the term for the two identical halves of a replicated chromosome?

• Sister chromatids

• Homologous chromosomes

• Centromeres

• Chromatin

The process by which a cell forms two identical daughter cells is called...

• cell division (mitosis)

• cell respiration

• cell differentiation

• cell metabolism

What stage of the cell cycle does the cell prepare for division?

• Metaphase

• Interphase

• Anaphase

• Telophase

What is the final result of the process of cell division?

• It creates two identical daughter cells.

• It creates one larger parent cell.

• It produces four genetically different cells.

• It results in cell death.

What is the function of spindle fibers during cell division?

• They help separate sister chromatids and pull them to opposite ends of the cell.

• They assist in the formation of the nuclear envelope.

• They are responsible for DNA replication during the S phase.

• They help in the synthesis of ribosomes.

What is the role of the spindle in the process of cell division?

• It holds the sister chromatids together and serves as the attachment point for the spindle fibers.

• It helps in the replication of DNA during the S phase.

• It is responsible for the separation of the cytoplasm during cytokinesis.

• It regulates the timing of cell division by controlling the cell cycle checkpoints.

During which stage of the cell division process do the chromosomes line up in the middle of the cell?

• Anaphase

• Telophase

• Metaphase

• Prophase
